"(Y/N)? Where are you going?" (Y/N) freezes, his jacket half way on.

"I'm going to a friend's house!" he looks over to Tooru who glares at him. "Aw, c'mon, Tooru! Can't I go?"

"Yeah, but you've been leaving all the time lately!" Tooru pouts before pointing over to Takeru. "You're leaving me with this brat. All he does is eat! He's no fun at all."

"I think I should be the one saying that I'm being left behind with a brat," Takeru mumbles, taking another bite from his milk bread cupcake.

(Y/N) slips out the house when Tooru starts to pout, rolling his eyes to himself. He gets on the bus and heads over to his boyfriend's house.

"Kei-chan!" he barges into his room after he's let him by the tall first year's mother. "I missed you!"

Tsukishima raises an eyebrow at him, turning in his spinning chair. (Y/N) takes it as an invitation to sit on his lap.

"I don't remember inviting you over," he says, wrapping his arms loosely around his waist.

"That's cause you didn't," he chimes back cheerfully, resting his forehead on his boyfriend's collarbone. "I heard today from Tooru that you have a practice match against my school. Do you want me to come and watch?"

"If you want," (Y/N) can feel him shrug his shoulders.

"Well, I was busy, but since you're just begging for me to come, I suppose I could-"

"Shut up, (Y/N)."

(Y/N) muffles his giggles against Tsukishima's neck.

-

"You're ditching practice?" Tooru sounds scandalized, when (Y/n) starts to pack up in the middle of practice the next day.

"I'm visiting my friend again," he sticks his tongue out at the setter. "And I'm not even on the team so it's not ditching."

"It better not be Tobio-chan," he hears Tooru grumble to Iwaizumi. He snickers, walking out the gym and starting to walk in the direction of Karasuno.

-

"Did you have to send a selfie of you and Kageyama to Trashykawa in the middle of practice yesterday?" Iwaizumi sighs, ruffling the first year's hair when he sees him at after school practice. "I think my ear drums burst with how loud he shrieked."

"Yeah, I did," (Y/N) beams, proud of himself. "So when's Karasuno coming?"

"They're here," Iwaizumi motions to the door that was just flung open by a small teen with a part of his hair bleached. Aoba Johsai lines up and bows, and Karasuno does the same.

"Oh yeah, Tooru-chan! The friend I've been seeing is that one," he points to the tall blond. "He's also not my friend, he's my boyfriend."

"That's him? The Karasuno first year?" Tooru asks, mortification clear on his face. "He's not even a hunk! He's a beanstalk! A skeleton!"

(Y/N) gave him a weird look. "You're a weirdo, Tooru-chan. Who cares if he's skinny?"

"If he's nice to (Y/N), I don't see a problem," Iwaizumi adds, whacking the back of Tooru's head.

There was a loud sniffling noise, and (Y/N) spins around. Both Mattsun and Makki suddenly have tissues and are dabbing at their eyes.

"They just grow up right in front of your eyes, don't they?"

"Yeah, our favorite Oikawa is ready to get some macking on!"

"I am only one year younger than you!" he gives them a disgusted look when they try to hug to him. "You guys are acting weird!"

"Wait.. favorite?" Tooru's brain slowly processes. "I'm not your favorite Oikawa brother?!"

"No," the whole team says in unison.

(Y/N) giggles and uses Tooru lecturing them all as an excuse to go over to the other team.

"Hi, Kei-chan," he wraps an arm around him with a large smile, eyes sparkling as he stares at him.

"Hi," Tsukishima says, feigning disinterest as he messes with his water bottle.

"You're boyfriends with him and didn't tell us?!" Hinata complains.

"He did tell us, you were too busy practicing your spikes," Yamaguchi pats him on the shoulder when he slumps over in defeat.

(Y/N) grins and looks back over to his brother's team.

"That is too much touching," Kyoutani grumbles. "What if he hurts him?"

"Challenge him to an arm wrestling match to assert your dominance," Mattsun snickers.

Iwaizumi hides his own smirk with a fist when Kyoutani agrees and Oikawa groans out, "What is even happening?"

"No," Tsukishima says, disgust clear on his face when Kyoutani approaches him and makes his intents clear. (Y/N) is doubled over with laughter, shrieks escaping his throat.

"Do it! Do it! Please, Kei?" (Y/N) snorts out loudly, slapping a hand at Tsukki's arm to try and get his attention as he remains slouched over.

"Stand up straight and I'll do it," Tsukishima sighs, tugging him upwards by the back of his shirt.

Tsukishima doesn't even try, letting his arm fall to the right as he stares blankly to the side. He stands up from where he and Kyouken were sitting, and (Y/N) is at his side in an instant.

"You did good!"

"I didn't even try."

"Oh.. you still did good anyways!" (Y/N) wrapped his arms around him, leaning the side of his head onto Tsukishima.

The Seijoh team looks on warily with calculating gazes, and Tsukishima tenses, staring back with carefully blank eyes.

"I like him. He's tall so that means he's hot," Makki says.

"That is not how it works-" Iwaizumi grumbles, and Kyoutani nods in agreement with what Iwaizumi says.

"Anyone under 6'0 is short-" Oikawa gets kicked in the side.

"Anyways, if he hurts (Y/N)-kun, he's dead meat," Mattsun grins when he hears his teammates agree. "Is that what I'm supposed to say? Whatever, let's start the match."

(Y/N) snickers and backs away from Tsukishima, giving him a thumbs up. "Good luck, Kei-chan. If you lose to my loser of a brother, I'm breaking up with you!" he goes back to Aoba Johsai's side.

"Was.. he joking, Tsukki?" Yamaguchi whispers, eyes wide.

"I have no idea."
