no thoughts only Tankhun in Arm’s shirt 😵‍💫

[29daffodils]

tong was in vegas and i find it so funny to imagine that after the coup and post-canon, tankhun tries going outside for longer distances and time and ends up in vegas only to grumble the entire time because he's supposed to be having the time of his life “but why is this city named after my asshole cousin?!”

arm : khun, actually it's your cousin who's —

khun : hush! i don't want to hear it! *proceeds to click 10 pics with different expressions and bombards vegas's phone with his displeasure, time difference be damned*

vegas : why are you texting me at 3:30 in the morning?

khun : you stole pete from me!! i hate you! why is this city named after you?!

vegas : actually

khun : I DON'T WANT TO HEAR IT!!

also, khun : *keeps grumbling but still has the time of his life*

Progression, Chapter 21: Preview

“Would you like me to call Pete?” 

“No!” Tankhun says, feeling a buzzing, hurt rage in his head as he updates his Instagram feed. Again. Still no pictures or announcements.

“Why haven't they posted anything?!” he says, tossing his phone to the side, “Pete just posted the kittens yesterday! Vegas posted a story of Pete helping him cook breakfast with a heart as the caption this morning! Where’s the baby? Vegas was NOT holding some doll in the cemetery, and he referred to Pete as Papa!” 

“Maybe they adopted her and it isn't finalized yet,” Arm says gently, “Or maybe they are fostering her and can't post pictures. We don't know the situation, which is why I am offering to call and ask Pete for clarification. We talk to him pretty regularly, and I don't see him keeping this from us unless he had a reason.” 

“The reason is Vegas,” Tankhun mutters, “He probably told Pete to not tell us. He's rude like that.” 

Arm lets out a sigh and takes his hand, “Tankhun. You have been worried sick about Vegas the last few nights-” 

“Lies!” 

“You said you thought Douglas hurt him too, and then you have been blaming yourself ever since,” Arm continues, “Why don't you…talk to him?”

Tankhun stares at his deranged boyfriend incredulously, “Absolutely not.” 

“You said you used to babysit him a lot,” Arm says quietly, “And when you made a mad dash out of the safe room to get to me during the attack-” 

“To save you, which I did!” 

“You crossed paths with him, and he left you alone,” Arm says, “And when we found out about him getting shot, you broke down and cried.” 

“Hmph!” Tankhun says, because it is much more preferable than admitting Arm is telling the truth. 

“He's been the main thing keeping you from actually hanging out with Pete in person, but he never stopped it from happening the few times it has occurred,” Arm says, now massaging his hand, “He seems to be very content out of the business as well, and you just found out you, Kinn, and Kim may share an abuser with him-” 

“We don't know if that's true,” Tankhun says, feeling his voice grow hoarse, “He may have just had to pee.”

Arm breathes out, “...And he just so happened to drive out of his way to a cemetery to pee on the freshly dug grave of a man associated with your family?” 

“...Fine. That is far-fetched,” Tankhun says, “Maybe it was a witchcraft ritual, and that is why he was so okay with us holding a fake seancé. Vegas had a fixation on witchcraft when he was eight! I still think he likes the aesthetic, to be honest, but when he was little? He and I would be dark witches, and Kim would be a nice witch. That's all he would play for a while. Uncle Gun hated it, but Auntie Milan thought it was funny, especially when Vegas made a Ouija Board and we insulted our stupid, dead grandfather through it because we both hated him-” 

“Tankhun,” Arm cuts in, “You're doing it again.” 

Tankhun tilts his head at that, “What do you mean?” 

“Talking about your cousin with fondness.” 

“I did no such thing!” Tankhun says with a gasp. 

“Lies,” Arm says simply, and that is true, but still! 

“Will you be okay with never knowing for sure if Douglas hurt him?” Arm asks, “Because I would understand if that is the case. There is a lot of bad blood, and the feud your father had with your uncle strained things between you and your cousins. If you want to keep your distance, I will support you. But I thought…I don't know. We have been together long enough-” 

“Two years in a little over a month,” Tankhun reminds him. 

“It's coming up very soon,” Arm says, a small smile forming on his lips, “You have opened up to me a lot during that time. More than you ever did when I was just your friend and your guard. So I know enough to know that at one point, you really cared about Vegas. Loved him, even. And when we found out about Namphueng, you told me you wondered if we had fought for the right side.” 

Tankhun looks away at that, “...I felt that way because Pa faked his death, let us mourn him, and got people killed. And because Kinn told me Pa kept Namphueng locked in a room and away from her sons. I also felt that way because he told me Uncle Gun saw her and cried, which wasn't like him. Uncle Gun wasn't good either. He became despicable too. But he wasn't evil enough to lock a woman up in a room and keep her from her family for years, let alone medicate her with...whatever she was being given."

Arm says nothing, and Tankhun understands. No answer Arm can give will be a good one. If he defends Pa, it undermines everything horrible he did, and how many lives were ruined or ended because of him. If he sides with Uncle Gun and Vegas, then it would ignore the fact that several of his coworkers died by their hands.

But there is no denying Pa is the one who set it in motion, regardless of what happened to any of them. He and Kinn were just expected to fight for their lives until Pa thought it was appropriate to make himself known, and they just went along with it because that was all they knew. 

And when he thinks about it that way, he supposes Vegas was in a similar situation and trying to meet his own father’s horrible expectations, that he was groomed by him, just like Pa tried his best to groom his own sons, albeit in a different way. 

Just like he might have been groomed by Douglas like Kinn was. 

Just like Vegas may have been threatened or hurt by Douglas like he and Kim were. 

“Ugh, I'm mad at you!” Tankhun says, jumping to his feet to glare down at Arm, “I don't want to talk to you for the entire night!” 

Arm’s entire face drops, “Khun-” 

“The entire night! You can sleep on the couch!” Tankhun reiterates, then storms off to his room and slams the door behind him. He shuts his eyes and tries to stick to his resolve. How dare Arm make him overthink their strained family ties? He is supposed to be on his side! Also, it makes no sense for Arm to encourage him to reach out, even if Vegas had been hurt. Vegas hurt and killed several of their guards. They may not have been guards Arm was close with, but they were allies and their lives meant something. 

Even though Pa clearly felt differently, since he triggered the whole attack purposely. 

Arm is so annoying! If he weren’t so smart, compassionate, gorgeous, and incredible, Tankhun would be DONE. 

Although, Tankhun supposes he has made mistakes of his own in the past. Arm has just taken them in stride, or sometimes worked with him on the occasions Tankhun expressed he would like to change the way he reacts to certain triggers. 

But that doesn't make him less annoying! Arm is supposed to be aligned with HIM, with Pol coming in second because Arm loves Pol as a brother and Tankhun loves Pol too. 

Just like they love Pete. And Pete is with Vegas, which makes that relationship strained because their relationship with Vegas is strained. And now, Pete and Vegas have a baby, and Pete hasn't said a word. That's probably because a baby binds him and Vegas together forever, and that means Pete will never leave Vegas. 

Especially if Vegas actually treats him well and truly makes Pete happy. 

Ew! 

“What are you still doing on the couch?” Tankhun asks sullenly as soon as he opens the door again. 

Arm meets his eyes and lets out a sigh, “I did pace for a little while and hover my fist over the door. But I wanted to give you space if you needed it.” 

“No,” Tankhun says, lightly stomping his foot, “I want you in here.” 

“Ah,” Arm says, standing up, “I must have misunderstood.” 

Tankhun nods once in agreement, then leads Arm to his bed so they can both sit down. 

Their bed. Arm stays here more than enough for this to be their bed. 

“I can understand your concerning willingness to make up with Vegas,” Tankhun says, “You just found out one of your best friends is raising a baby with him. Of course you would like to extend an olive branch. Of course you would like to hang out with Pete in person a lot more. I get it, because…because I want those things too. It's just hard.” 

“I know.” 

“And…” Tankhun continues, swallowing the sudden lump in his throat, “The thought of getting Vegas’s confirmation that Douglas hurt him upsets me. I used to babysit him when he was younger. I used to adore him, and I know there is no point in denying that. So if he admits Douglas hurt him too, that means I failed him as well, and I don't know if I can handle that.” 

Arm puts his hand on his back and rubs it, “Would you be able to handle never getting a confirmation, always wondering, and just continuing to have weekly FaceTime chats with Pete? Or is that preferred over finding out what Vegas went through and possibly...mending things? I don't know if that's possible, but it might be a step in the right direction if the issue is thought out and approached in the right way.” 

Tankhun thinks on it, then breathes out, “I think it should be Kinn who reaches out. That would be the best way to go about this.” 

Arm looks slightly startled by that, “But he hates Kinn the most-” 

“But Kinn was also hurt by Douglas the most,” Tankhun interrupts, “And if Douglas actually managed to hurt Vegas, he may be bitter over the fact that Kim and I fought back and managed to get out of whatever Douglas planned to do to us. And if he got away from Douglas like we did, I…As much as he resents Kinn, I can't see him being happy about a fourteen year boy being sexually assaulted. I can't even see him being happy that Kinn went through something like that, because at one point, he loved Kinn.”

“...Do you think Kinn would be willing to admit that to him?” Arm asks. 

“I don't know,” Tankhun groans, “Probably not. But Porsche is in contact with Pete and Vegas and visits them. Maybe he can help set up and facilitate a conversation like that. I just…Fuck, Arm! You are SO annoying!” 

“You have said that before,” Arm acknowledges as Tankhun pulls out his phone. He sets up a group chat with Kinn, Porsche, and Kim before adding Chay at the last minute. Chay games with Macau and talks with him. Maybe that connection could provide a backup plan that Tankhun doesn't fully have formed in his head yet. 

But regardless…

Tankhun: I need to have an important meeting with the four of you. Kim, Chay, I know you two have been working on music all day, but please take a short break. I hope we can come to a decision about this and move forward with my plan within the next couple of days.

Kim: What is this about? 

Porsche: It sounds serious. There are no emojis. 

Tankhun: 🎾🐁🌬️🎫📟🖨️🩻

Kim: You never even use any of those. 

Tankhun: That's because I need to have a serious conversation with all of you. Come here. Now. Kinn, you too. 

Kinn: Is everything okay? 

Chay: What do you want to talk about? 

Tankhun takes a moment, then types one word. 

Tankhun: Vegas.

Tankhun: 🎰

Rating KinnPorsche ghost ships:

PetePorsche - 10/10

Adorable, amazing, brilliant, showstopping, spectacular! Best friend to lovers to soulmates for the win. Really pure ship. What else is there to say? Pete and Porsche will sneak away on little dates, mostly to eat and smoke. They will be partners in crime to all sorts of crazy ideas. Pete will definitely go and open a restaurant by the beach with Porsche. Pete and Chay will be best friends. Chay will also have to be the mom of the group because the other two morons don’t know what self preservation is. Pete’s grandma will be so happy that Pete has found such strong and beautiful boyfriend, she will start sending food to feed a small army claiming Porsche and Chay need to grow even stronger.

MacauChay - 7/10

Love them! I really do! But those little gremlins will kill each other if they date. I see why people ship them. They’re both from a broken family with only one brother to rely on. They’re both trapped in their circumstances and may find comfort and understanding in one another. They will absolutely hate each other at first, though.

ChanBig - 10/10

Did someone said Daddy Chan? I think we all saw that scene in ep1 and we collectively went - yep, they fuck. It’s the way Chan has all the power, the way Big doesn’t want to disappoint him. My daddy issues could never. It’s their power dynamic, it’s Big refusing to look at Chan’s eyes, it’s Chan being firm but gentle. I don’t need to say anything more, there are already amazingly slutty fanfics about them.

VegasTay - 10/10

This ship gets bonus points for the aesthetics alone, they are both gorgeously styled. I can see it happening as a one night stand. When Tay has finally had enough of Time’s bullshit, he goes to a club and sees Vegas there. Tay is ready to make some bad decisions. Vegas on the other hand has no idea what is happening, but one of Kinn’s best friends is flirting with him and he’ll be a fool to miss that opportunity. Vegas wrecks Tay’s world that night. Tay tells him he can leave marks. Vegas knows that his definition of “marks” is different from most so he controls himself. It will be so much more satisfying if Kinn’s friend does not regret this in the morning. Afterwards Tay tells the story of his shitty relationship and Vegas suggest murdering Time. Tay should have found that calm statement frightening, but he didn’t. He actually found it quite funny. Having his friend’s hot psycho cousin care more about his feelings than his actual boyfriend. Tay suggests doing that again, gathers his things and leaves. Vegas doesn’t know why he never told anybody about that night, maybe he forgot.

ArmKhun - 8/10

I’m taking points out because of the power imbalance and I’m giving points back because of the aesthetic. Diva Khun and Bodyguard Arm! Yes, give me more. The scene of them fighting the minor family with Arm’s car-bombs which were bedazzled in gems by Khun is what sealed the deal for me. They are an amazing team. Khun is such a fun and crazy character and I would like to see him in a more serious situation. What if he gets a gun pointed at him and goes into a ptsd episode while Arm has to be the best bodyguard and protect him but also later calm him down. The crack but also angst potential is astonishing.

KenBig - 6/10

Someone said they are the Mean Girls of KinnPorsche and it hasn’t left my mind since. Yes they are! Them just gossiping around and making everyone’s life miserable, love to see it. Don’t know if I can see them as something more serious than fuck buddies but I see the angst potential of both of them dying without knowing about what happened to the other.

ArmPorsche - 7/10

I’m seeing this starting as one sided love because notice how Arm looks at Porsche, that boy is in loooove! He was ready to go against his boss just to help Porsche. If Kinn was actually cheating on Porsche, those two boys would be game.

KinnPete - 6/10

Pretty sure this ship became famous after VegasPorsche left KinnPete in the dust in that alley. I can’t see this ship working, surprisingly because Kinn is a cinnamon roll when he’s in love and Pete is a psycho when he’s in love. But there is something really homoerotic about Kinn having trust issues and Pete being the only one he trust unconditionally. I can see it if the story takes a “dead dove do not eat” approach. With Porsche betraying Kinn and Kinn turning dark, and Vegas betraying Pete and Pete turning desperate.

Hello!

You just posted a lovely ArmKhun fic—they’re such a fun rarepair. Do you have any dearly-held headcanons for these two?

Hello!

I'm so happy you enjoyed my Arm/Tankhun fic — they are one of my favorite KinnPorsche rarepairs and the first one to really capture my heart while I was watching the show!

I'm thrilled that you asked this because I have SO many headcanons for these two, both separately and together. In no particular order, they include:

Tankhun picked out Pol and Arm to be his bodyguards because they are the tallest bodyguard and the shortest bodyguard respectively, and he finds their height disparity amusing. The fact that their personalities meshed well with his was a complete coincidence.

I have backstory headcanons for all the bodyguards that I have imagined so vividly at this point that sometimes I forget they're not canon. My headcanon for Arm is that he was in the military for a couple years before Chan recruited him to come work for Korn. That's where he got his weapons-handling training. It also means that Arm is a trained field medic, which you can see in the way he rushes in when Porsche has been drugged and when Big [rest of sentence lost in incoherent sobbing]. He has some experience helping people manage PTSD because of this, which gives him real empathy for Tankhun and makes him essential when Tankhun's in crisis.

After Kinn announces that he's in love with Porsche, Tankhun marches directly to the equipment office and is like ARM DID YOU KNOW ABOUT THIS?? Arm, who has been catching them on the CCTV for weeks and is dying to talk about it with someone, already has a highlight reel of "Kinn and Porsche being unsubtle all over the house" edited together and ready to go (he's kept it PG-13 because he's classy like that and because he doesn't want Kinn to actually murder him). Arm and Tankhun watch the whole thing together with popcorn and much squealing in delight and horror, following which Tankhun storms up to Kinn's room like KINN! WE EAT ON THAT TABLE KINN!

Arm grew up watching lakorns with his mom and grandma and loves them. I mentioned this in Brave Enough for Everything but he's the only bodyguard who actually doesn't mind all the TV.

I also alluded to this in the fic, but Tankhun finds Arm's street clothes genuinely, painfully distressing. After they're together, they have a protracted battle about the degree to which Arm is willing to let Tankhun dress him, which results in Arm staying a lot more normcore than Tankhun would like but at least he's wearing some bright colors sometimes and his clothes fit him properly now.

Arm and Tankhun stayed up all night making the glitter-bomb robots from the finale. Tankhun thought his dad was dead and knew they were on the brink of war with the minor family, and Arm invented this Battle Craft basically on the fly to give him something to focus on and keep him from spiraling out.

Speaking of which — do you ever think about how in the finale, when Erika comes out with guns blazing, Arm and Tankhun are right there in the office behind her? They're in lockdown right behind that wall, listening to their friends and Tankhun's brother get shot at, watching on the CCTV. There's no universe where Arm isn't holding Tankhun tight for all of that.

I know there are more — I could talk about these good good boys all day — but this is getting long and those are the ones off the top of my head. What are your favorite ArmKhun headcanons?

[everybody-hit-the-pyro-cue]

What Tankhun did have; however, was the most extensive sex toy collection in Bangkok. In whole Thailand. And no Pete meant no one Tankhun could trust with organizing, restocking, and cleaning his toys. As Pete was busier with Vegas' collection, even if it clearly dwarfed in comparison. No matter what others said, Tankhun couldn't just outsource this role to anyone. He was very aware how pathetic and lonely his collection would make him look in their eyes. Pete had suggested to let Arm take over his duties. Ridiculous. Arm? Ex international beauty pageant Arm with his perfect body and stupid perfect face? Smart as a whip and cute as hell? Tankhun would join Elisabeth and Sebastian from the embarrassment.

 In which Arm is jealous, Tankhun feels unloveable. Eventually, they fuck about it.

[imacelestialbeing]

Tankhun and arm should get married already. I would also like them to be my besties and arm to let me borrow his toy cars. They better get more screen time in s2.

FOR THE LOVE OF GOD IF YOU SHIP ARMKHUN PLEASE GO READ THIS FIC!  It’s amazing!  It’s the greatest slow burn for this couple that I have ever seen and I’m feral for it! Please go give it some love!!!

But absolutely you need to heed the tags. First and foremost, take care of yourselves!!!

[kinnbig]

perhaps........ 60 for armtankhun?

60 - mistletoe kisses - ArmKhun ✨

[29daffodils]

listen, the whole of the Masks series can give the original KPTS a run for its money.

it is so well written and weaves divergent lore into canon in such a way that sometimes i forget I'm reading a fic instead of say, the original novels (I've heard they are pretty shit, no offense).

anyway, go give Masks a try. it's the best thing ever!

[ae-azile]

KP Question of the day:

Your favorite KP ships (both canon and not canon) are ready to propose. Who is proposing to who, why is it likely one character proposing over the other, and how are they proposing?

I'm gonna start with ArmKhun.

I see Tankhun proposing to Arm. I could see him throwing himself into planning it in order to make it perfect, aesthetically pleasing, and romantic, but also keeping it private because he thinks Arm will appreciate the intimacy of a private proposal. I also think he would want it private due to how many people have perceived and treated him post-kidnapping. While he loves seeing big, beautiful, and public proposals on YouTube, he feels like he doesn't need to put on a show with Arm and wants to keep it that way in order to keep the proposal genuine and heartfelt. But he would totally shell out money for a ring that fits Arm's interests and style, as well as on decor to make the proposal location stunning.

The wedding it going to be gorgeous as well, and the reception will be wild. So wild that they may delay their flight to their honeymoon destination for a day to recover from their hangovers.

Feel free to reblog with your own headcannons on different ships, on a differing take for ArmKhun, or send asks requesting other couples!

[ae-langan]

So, I'm writing a semi-crackish fic in the KinnPorsche fandom. It's somewhat hard to describe, but currently in the fic, Vegas is drugged up on pain medications and is completely fine with Tankhun, Arm, Kim, Chay, and Porsche visiting his hospital room to play Nintendo Switch. While I do have a Nintendo Switch, I only play it sporadically. So this question is for anyone else in the KinnPorsche fandom: What games would you like to see them play? I have a few in mind, but would love to hear your opinions. The more off the wall and weird, the better.

[legendaryrooftopscene]

One of my current wips is 17k which doesn’t feel like a lot but I just added page numbers to my document and it’s 60 pages. Which feels like a lot.

[giraffeter]

Hi again ^^

Thank you for that delicious ArmKhun headcanon answer. I have an immediate follow-up ask. You mentioned that you have vivid background headcanons for all the bodyguards, as if that isn't a massive tease. Any details you'd be willing to spill? 👀

Haha I suppose that was a bit of a tease! Your asks keep making my DAY, I will happily talk about these boys all day every day.

OK, the Giraffeter Bodyguard Backstory Headcanons are:

Big: I alluded to some of this in Gonna Fade You Like That Rush, but in my mind Big is the son of one of Korn's lieutenants — his dad works for Korn, his grandfather worked for Korn's father, the families go back. We know that he's one of Korn's hand-raised bodyguards and that he and Kinn grew up together; I think Korn would not be interested in caring for a bunch of additional children, so my headcanon is that his hand-raised boys stay with their families of origin until they've completed their mandatory schooling, which in Thailand is through Grade 9 — Big would be 14 or 15 when he came to the main family house and began his training. Big is the younger son in his family: his older brother will inherit their family's piece of the Theerapanyakul criminal empire, and Big's been marked for Kinn for basically his whole life. Even before Tankhun's abduction, Big belonged to Kinn. He met Kinn for the first time when he was about 12 and Kinn was 15 or so — Kinn was the coolest Cool Older Teen Big had ever laid eyes on. He smiled that devastating smile at Big and talked to him about video games or something and Big plunged headfirst into a fealty kink that would last the rest of his brief life.

Ken: As much as I have read and enjoyed many fics shipping Ken with various other male characters, my favorite headcanon for Ken is that he is the "token straight" in the main family house, and as such is relatively immune to the psychosexual shenanigans taking place on all sides of him. He's from a fairly well-off family — he grew up in Thailand but went to an international school, and he went to college in Australia. He was a competitive swimmer all through high school and college, which is why the "nice one, loser" moment cuts so deep. He has that very dangerous trait of "smart but not as smart as he thinks he is" in addition to being pretty greedy and amoral, so my headcanon is that he was boosting cars or some shit and stole the wrong car. Chan gave him a choice of "well-paying job for life or bullet in the head right now" and he happily chose the former. He thought working for the mob would be a lot more glamorous and exciting than it turned out to be; that, combined with aforementioned unwarranted self-confidence and greed, was what made it so easy for Gun to turn him.

Arm: I covered this in my answer to your delightful previous ask so I'll be brief here, but my headcanon is that Arm is ex-military and a trained field medic, and has some experience being around PTSD.

Pete: Pete is another one where we actually do know a bit about his backstory: the abusive father, the loving grandma, the complicated relationship to food, the history as a boxer. I don't understand Thai well enough to verify this but when Pete says "boxing" I assume he means muay thai. Pete is a real country boy, and I think he didn't spend much time in Bangkok before he came to work for Korn. I think he dealt with some food insecurity as a kid, from a combination of his dad not having much money and also just not being around much to feed him — I think his grandma (who I think he calls ยาย meaning she's his mom's mom?) took care to feed him up as much as she could when he visited her. My headcanon is that Korn straight-up bought Pete, either for cash after seeing him fight or as payment for a gambling debt his dad owed Korn's organization.

Pol: I think Pol was another one of Korn's hand-raised bunch, although his background is different from Big's. I don't think his parents are directly involved in the criminal underworld in the way I imagine Big's as being; instead, I think they're just regular working-class people who own a business, maybe a shop or something, that comes under Korn's purview. We've seen that the Theerapanyakul empire contains as many legitimate enterprises (bread company!) as illegitimate, and we know a lot of their money comes from real estate, so it might be as simple as Korn being Pol's family's landlord. Maybe they've been tenants of his for a long time, since his dad was still in charge; maybe they were part of the first territory he controlled while he was working his way up. At any rate, at some point when Pol was growing up Korn said "I have a job for your son if he wants it;" now Pol lives in the fancy house, has nice clothes and all his meals provided, and makes more money than his parents do by a long shot. He's the only one of the main bodyguard squad with a good relationship with his family (Pete and his grandma notwithstanding), which is why he's always on the shared phone.

Thanks for the ask! It was fun to write all this out after carrying it in my head for so long!
