#in the end roksu might just run away with his hyung

[idontknowmyownmind]

RokCale brother AU:

KRS reincarnated as Cale's younger brother and because his first life is more fucked up than canon, he become unhinged in an obsessive way toward Cale, codependency and attachment issue at best

Cale is older by 5 years than Roksu and he basically Roksu's primary caretaker since their mother's death

Roksu is a sly and manipulative kid, always monopolize his hyung's time and attention

He doesn't like to share and want to keep his brother for himself, even from their family

Roksu resent Deruth who 'hurt' Cale, although not openly show it

He harbor ill feeling toward Basen and Violan who made Cale 'sacrifice' himself

But Roksu never trully hurt them, just make their life a 'little bit' difficult because he doesn't want to make his hyung sad or upset for seeing them 'hurt'

Ron is the only one who is aware of Roksu's darker side because he always with the brothers

Let's say that Roksu 'threatened' him to keep quiet

Roksu never let people get to close with Cale nor he let his hyung attached to someone other than him

It's subtle but Roksu always isolating Cale from other people whose not him

People know Roksu as a silent but good and obedient kid while they see Cale as the unruly brother

In a way, Roksu also adding fuel to rumor regarding Cale so no one ever approach him to take him away

“So, babysitting?”

Alberu follows after the delinquent. From the record the vice-principal gave him access to, Cale frequently drinks alcohol, he often gets himself into a lot of fights, and he barely passed his classes at the end of the grading period. The teachers never call on him in class, girls and boys avoid him alike, and he is- supposedly- completely intolerable.

Which is why Alberu Crossman, who’s only a little older yet infinitely more mature has been assigned by the principal (his father) to get the troublemaker under thumb. Cale's father is quite wealthy, actually, and since there isn't much known about the successor to the Henituse family... it'd be bad if he had to be expelled.

Cale scowled. “Yes, babysitting, your highness. Please, leave if you must,” He jeers at Alberu, but internally he thinks, 'No, really. Please leave.' Otherwise, he might get caught in the act.

Of not actually being Cale.

Roksu aims a sour expression at Alberu, who returns it with a more flowery one. Acting as his twin for the day had been easy enough, mainly because being trash is great!- until Alberu Crossman strolled into his lunch period and introduced himself.

He is even following him out of the school to his job. Well, this job is Roksu’s and not Cale’s, but because he can’t ditch work nor can he get glib-tongued Alberu off his tail-

Well shit.

Thankfully, the kids call him hyung. Except Raon, who calls him human. Hopefully Alberu doesn’t look into it too much. If everything goes right, Alberu Crossman will be Cale's problem to deal with tomorrow. As it should have been.

“I didn’t know you liked kids, Cale,” Alberu smiles charmingly, walking side by side with Roksu. “Can you introduce me?” Roksu struggles to not put on his own disarming smile out of spite, instead plastering on a classic Cale Sneer™. It fits on his face perfectly, like he’s playing a character in a play.

They enter the building and ‘Cale’ guides Alberu to a colorful playroom, decked out in toys and a fountain of running water as the centerpiece (A gift from his father, who is still upset that Roksu doesn't visit more often). There’s a tray of fruits and oatmeal on the small table in the corner of the room, except not a soul to be seen. Picking up a bowl of oatmeal and finding the ceramic to still be hot, Roksu almost smiles.

Alberu frowns. Where are the kids he's supposed to babysit?

Roksu tells the empty air, "Come on out."

Three children appear out of nowhere in front of them.

“Hyung!”

“Human! You’re back!”

“Hyung, nya.” On examines Alberu some more.

All of the kids had been revealed the moment that Roksu spoke, as Raon unveiled the invisibility on them.

Raon runs up and grabs Roksu’s hand, who places it on his head, rubbing the black hair comfortingly. “Mm.” Raon beams at the affection.

“Raon, On, Hong,” they each look up at him at the call of their names. “This is Alberu Crossman, he is doing a report on my trashy behavior. Don’t be rude."

All three children become hostile immediately. “He isn't trash!”

On observes Alberu with an intense glare. Raon shifts under Roksu’s hand, his deep blue eyes glinting with magic. Roksu positions him away from the older teen’s view. Raon grips onto Roksu’s pant leg with a vengeance. Hong stares openly, offensive.

Alberu smiles at them.

"I'm visiting with Cale Hyung for today, nice to meet you."

Hong gasps suddenly.

“He-!” On gives her brother a look, and he clamps his hands over his mouth. Alberu feels a deep curiosity, as if something isn’t quite as it seems.

Roksu sighs. It’s going to be a long hour.

At the midway point, Alberu has easily disarmed the children. They look fascinated at the magic he shows them, while Roksu can only rub a palm over Raon’s shoulder as a warning to keep his dragon magic under control. He's still just a child that wants to brag. Everything is going well.

Bang!

“Hey Roksu! How was-“ Cale bursts through the door, bright red hair equipped with a shit-eating grin, wearing clothes far less fancy than his usual. He tenses up, frozen in place when he spots Alberu on the floor, politely sitting "crisscross applesauce" with the children. Roksu narrows a withering glare at his twin.

“… Roksu?”

Alberu looks at ‘Cale,’ sitting next to him, the one he's spent the entire day with, who is trying to send what must be the real Cale into the sun with his eyes.

“Ha… ha?” Cale winces. Roksu wipes his expression from his face.

“Cale-hyung, run! That’s the human’s bad look!” Alberu’s eyes widen as he watches the confirmed real Cale bolt back into the hallway and out of the front door. Alberu whips his head back toward the stranger behind him, who is a perfect replica of the Cale who ran like Hell. Cale has an identical twin?? Since when? Why doesn't he go to school?

Roksu levels an emotionless gaze at Alberu. “Hello, your highness. Don’t mind me.”

Alberu can only watch in astonishment as this stranger walks out of the playroom, with a smooth and deadly gait as he hunts down his twin like a predator would to prey. He recalls the look 'Roksu' gave him and it sends a shiver down the principal’s son’s spine. That gaze held secrets.

Something about this stranger is even more interesting than the sudden appearance of a twin.

On walks up to him, sitting down in his lap and looking into his eyes. “Roksu-hyung will be back soon, nya!” Hong bounds over and sits next to his sister, grinning widely. Raon huffs and looks at the door. He wants his human to come back.
