interruption // tachiaku sickfic

ao3!

Ryuunosuke is really starting to regret this trip.

He's only come along because Gin was so excited about the idea of him coming. She's his weakness. He can never say no to her, not even if it's doing something dreadful like sitting in a car for five and a half hours.

Normally, this isn't an issue. Higuchi drives him places all of the time, but Ryuunosuke is always in the passenger seat. This time, he's given the seat up to Gin so that she can sit with Higuchi up front, who offered to drive them.

Ryuunosuke supposes he never realized until now just how carsick he really gets.

They're chatting about something up front that Ryuunosuke can't focus on at all because of the music. They’ve been driving for about two hours at this point, and the trip is only halfway over. He’s hoping he might get lucky and they’ll stop somewhere so that he can reset for a moment, but he doesn’t want to alert anyone by asking to stop.

"You okay?" Tachihara asks him quietly, as to not alert the girls up front. He’s been quiet most of the drive too aside from quipping into the girls’ conversation, and he’s sat next to Ryuunosuke in the back seat.

He is definitely not okay, but at this point, if he opens his mouth to answer Tachihara, he's certain that vomit will come out before any words do. He's not sure what to do. His head hurts. He feels so sick that he can't focus on anything, and he thinks he might die from embarrassment if he vomits in Higuchi's car, in front of his sister and the guy he may or may not have a massive crush on.

But of course, the universe does not care, and the gag that's forced out of his mouth isn't enough of a warning before he throws up onto the floor mat beneath the seat.

He's mortified. His ears are so hot he thinks they might fall off, and he's shut off everything around him. He knows Tachihara is saying something and he feels his hand on his back, but the words are lost to him. He chokes up another mouthful of vomit and now he's worried about crying too. He never cries in front of people. He can't start doing that while he's also throwing up in the car with all of them.

His arms are wrapped around his middle and he’s doubled over and every other sensation is completely lost to him. He can’t even tell if the car is still moving or not, and his eyes are screwed shut because he’s afraid that looking will make him even more sick, but he’s slightly concerned that opening his eyes will provide him with no sight.

His throat burns so badly and his abdominal muscles are already sore, and he doesn’t feel any better than he did before he threw up. This is such a nightmare. He would rather die than open his eyes right now. Normally he would simply move on and pretend this never happened, but he doesn’t think that’s possible here at all. Not only does he still feel awful, but he’s trapped in this car with nowhere to hide or run off to.

"Hey, hey, can you hear me?" Tachihara says. That's the clearest his voice has been in what feels like at least half an hour. "It's just me. I told the girls to go inside. But they're super worried about you."

Ryuunosuke wants to answer, but he's too scared to open his mouth again. His hands move to cover his face and he’s starting to realize that the car has finally stopped. He isn’t entirely sure what Tachihara means by inside, but he has to assume they’ve stopped somewhere.

Maybe they didn’t notice. That’s a completely delusional thought, but it gets Ryuunosuke to sit up.

"Here, let's get out of the car. You need fresh air," Tachihara says, climbing out of his side to meet Ryuunosuke on the other side.

Ryuunosuke takes his hand. His legs are shaking so much that he can hardly stand on them, and it's making breathing a lot harder, too. He still feels terrible. Never in his life has he been this carsick before, but he doesn’t think he’s ever been in a car for this long, either.

Tachihara doesn’t lead him too far off, just to the hood of the car so he has something to lean on. Ryuunosuke still can’t bear to look at him.

He hears Higuchi’s voice and resists every urge to curl up into Tachihara’s side and pretend he’s not even there, but he has to face the consequences, whether this is something that was completely out of his control or not. Surely there was some way to prevent it.

"Higuchi, I -"

"It's completely fine, I promise," Higuchi says. She’s already completely ahead of him, of course, as always. "I can just throw the floor mat out. It's really not a big deal at all!"

“Are you okay, Ryuu? Do you feel better?” Gin asks, tilting her head in some attempt to get Ryuunosuke to look at her, but he can’t do it. He can feel his face start to get hot again.

“I’m - I’m fine,” he insists, because there’s no other acceptable answer. Clearly, he’s worried her enough.

"C’mon. Let's get you walking around, you'll feel better that way," Tachihara tells him as he takes his wrist and leads him away from the car. “We’ll be back.”

The lights in the gas station are entirely too bright for the headache he’s trying desperately to will away, and the nausea starts to bubble in his throat again. He silently looks around for any sign of a restroom, that way he can at least vomit with some dignity.

He was hoping for privacy too, this time. Ryuunosuke doesn't expect Tachihara to follow him inside, but it must be obvious enough that he's about to vomit again.

He almost collapses completely in front of the toilet but Tachihara manages to keep him upright enough for him to bring up a mouthful of vomit with a weak burp. He’s hardly eaten anything today, but his stomach doesn’t seem to care, it’s simply trying to evacuate any trace of anything to punish him for being in a car for so long. What is he going to do? How is he going to last the rest of the trip? Is he going to feel this sick the entire vacation, too?

"You should've said something. You know Higuchi wouldn't have minded pulling over,” Tachihara tells him. Ryuunosuke has barely registered that he’s knelt beside him with a hand on his back. He really never pegged Tachihara as the type to do this, but he’s sort of glad for it, because it helps, somehow.

He takes a few breaths before he speaks to make sure he's clear to talk without throwing up.

"I didn't want to interrupt them," Ryuunosuke mumbles, gathering a wad of toilet paper to wipe his mouth. His hands are shaking so much that Tachihara has to help him tear it off. "I didn't think…that would happen."

"You looked nauseous to me the whole time, Akutagawa. I'm surprised you even got that far," Tachihara sighs.

Ryuunosuke's shoulders sink. He didn’t think it was that obvious, but apparently, most times he thinks he's hiding any condition of his from these three, they all already know.

He thinks he's okay, now, but he doesn't want to stand up. He decides to sit against the wall beside Tachihara. It's nice to just have solid ground beneath him for a while, not having to worry about moving or walking around.

"I'm sorry for the trouble I've caused," Ryuunosuke tells him. He's not sure how he can repay him for this help. Ryuunosuke doubts he would be anywhere near as helpful if their places were switched. He really is grateful, but he feels equally as guilty.

"It's seriously nothing. I'm sorry you're the one who's gotta feel like shit," Tachihara tells him. Ryuunosuke's getting sort of distracted by his eyes. Tachihara says something to him again, but he doesn't hear it, he's lost for a handful of seconds. He's only taken out of it because he feels Tachihara's hand on his forehead. "You don't feel all that warm, you okay?"

"Ah - I'm sorry," he stammers, embarrassed as he turns his head away, "I supposed I'm just out of it…"

Tachihara seems to want to say something, but he's interrupted by a buzzing in his pocket.

"Hold on. Higuchi's calling me," he says, answering the call. Ryuunosuke hears the woman's distressed voice but he can't catch what she's saying. "Oh, sorry. We're in the bathroom,"

"Suspicious," she says, Ryuunosuke catches that much, and his ears start to feel hot again.

"Okay, hey, no. We'll be out in a second," Tachihara grumbles before hanging up. He stands up and offers a hand to Ryuunosuke. "I'll help you up, you're still not super steady."

Ryuunosuke turns his head but takes the hand and Tachihara helps him off of the floor. It's sort of dizzying, maybe he should have taken it slower, but Tachihara takes his arm to steady him.

"You okay, Akutagawa?" he asks, uncomfortably close to Ryuunosuke's face. He just nods and turns his head away, hoping that Tachihara won't notice how red his face must be.

Tachihara says he'll buy them some waters and orders Ryuunosuke to go back outside and get some fresh air, which he certainly doesn't have any objections to. He doesn't entirely remember where they parked, but he spots Gin and Higuchi leaning on the hood of her car. They're giggling about something. Ryuunosuke's glad he didn't ruin their time entirely. He wishes they would just pretend nothing happened, but they've never been the type to do that.

Gin takes notice of him first as he approaches the car, and any bit of a smile that was on her face before is wiped off. She looks so concerned. Ryuunosuke wishes he could wipe her memory.

“I’m sorry,” Ryuunosuke manages to say as he turns his eyes away.

"No apologizing," she insists.

"It's really not a problem," Higuchi chimes in. Ryuunosuke's grateful she feels that way, but he's not quite sure he can agree.

"I found this inside. You should take one," Gin says as she hands him something from her jacket pocket. It's a medication labeled for motion sickness. "We'll wait half an hour so it has some time to work."

"Oh…thank you, Gin," he says quietly. He didn't even know this was a thing.

"I don't remember you going to the register," Higuchi says, sounding rather suspicious.

Gin doesn't say anything, but her silence heavily implies she stuffed it into her sleeve and slipped out.

"You're so scary. There's so many cameras in there," Higuchi groans, but of course, Gin is a professional shoplifter. She doesn't even bother to address the accusation, she takes the sheet that Ryuunosuke is struggling to open and pops out one of the tablets for him.

"We don't have to wait. I don't want to be the reason we're late for something," Ryuunosuke says after he swallows the tablet. He doesn’t think he’s quite ready for it yet, honestly, but he feels guilty holding everyone up. Besides, he’s almost certain he has nothing left in his stomach to bring up, anyway.

"We didn’t plan anything today because of the drive,” Higuchi assures him. Ryuunosuke realizes they won’t let him feel guilty no matter what.

Tachihara appears with a few water bottles and hands them off to the group. Ryuunosuke gingerly takes it. He’s not sure he really wants to drink any, but Tachihara takes it from him to open the cap and hand it back, giving him no choice.

They loiter in front of the car for a while, and Ryuunosuke ends up sitting on the pavement to lean against the front of the car while the three of them talk. He feels better, he thinks, but his body aches and there’s a dull throb in the back of his head. The cool evening breeze eases it just enough to where it’s not causing too much of a problem. He’s starting to get tired.

"Do you feel better? Your color's starting to come back," Gin notices, suddenly knelt down in front of him. He hasn’t paid much attention to the time passing, but the half-hour Gin mentioned must be up already.

Ryuunosuke simply nods.

“Okay. Please tell me if you’re not feeling good, okay? Tug on my sleeve or something. Or text me, I’ll keep my phone on,” Gin tells him. Ryuunosuke really feels terrible for how much he’s worried her. “You can sit up front instead.”

“No - no, it’s fine,” he insists. “I’ll try to rest in the back. I’m starting to feel tired.”

Gin pouts. “Are you sure?”

Ryuunosuke nods again, and Gin helps him off of the ground.

He climbs back into the seat he was in before and finds that the floor mat really is gone. He tries to ignore the thought as much as possible because his brain is trying to convince him he’s nauseous again at the memory of how he threw up earlier. He needs to focus on something else. He needs to try to sleep, if he can -

"You can lay down, if you want to," Tachihara says. Higuchi’s turned the car on and Gin is getting something out of the back, and she calls her over. So now it’s just them, for a few seconds.

Ryuunosuke isn't sure he can even do that without getting in Tachihara's way. There's not much room in the back, unless he lays his head in Tachihara’s lap. That’s not what he’s implying, is it?

“Are you - “

Tachihara’s hand snakes behind Ryuunosuke’s head and gently lowers him down so that his head lays in his lap, and it’s not much different from finally lying in bed after a needlessly long day - he feels relaxed. Safe.

"Thank you," Ryuunosuke says quietly. He's already starting to feel tired. He's not sure if he's just exhausted from his whole ordeal, or if it has something to do with the way Tachihara rakes his fingers through Ryuunosuke's hair - he's going to pretend he doesn't feel a certain way about that.

Ryuunosuke manages to fall asleep before Higuchi even pulls the car out of the parking lot.

"He has a huge crush on you," Ryuunosuke hears Gin say in a moment where his brain briefly wakes him back up. "And you better be nice to him. He's going to be embarrassed about this for the rest of his life."

"Have I not been nice to him? Ugh," Tachihara says. Ryuunosuke isn’t sure how much time has passed, but Tachihara’s hand is still on his head, patting it every now and then. He tunes out the conversation as it continues and manages to fall asleep again, hoping he imagined Gin telling Tachihara his secret.
