Chapter Text
It was a normal weekend at the Tsukishima household, Tsukki and Yamaguchi were studying together in Tsukki's room, they usually studied together on weekends, nerd stuff. Tsukki was a little quieter than usual, not saying that he wasn't already quiet, because he is, but usually he’ll make snarky remarks if he sees Yamaguchi mess up on a question, but there was no teasing today?
Odd.
“H-Hey tsukki?” Yamaguchi murmured, “Mhm? Somethin wrong?” Tsukki replied, “You just seem a bit..off, did something happen?” Yamaguchi questioned, sweet boy.
“Yeah, I'm good..just um, my cousin is gonna be living here soon..” Tsukki answered, huffing slightly, picking a thread on his pants.
“Woah! I didn't know you had a cousin, are they cool?-what are they like?” Yamaguchi exclaimed.
"They're annoying, you wouldn't like them, they're a pain in the ass.” Tsukki grunted, crossing his arms.
“Tsukki! You say that about everyone! When do they get here!?” Yamaguchi exclaimed once again, getting worked up over nothing,
“God..you're so loud, they'll probably be here in a few minutes, they only live a few towns over..” Tsuki groaned, “I had to spend all of last night cleaning out the guest room for them..” He complained, the sound of a car pulling up outside made Tsukki and Yamaguchi's eyes snap towards the window, “Speak of the devil..” Tsukki groaned again, sitting up slowly, standing fully and heading for his bedroom door, he glanced back at Yamaguchi, “You coming or what?” Tsukki questioned with that sarcastic tone in his voice,
Yamaguchi jumped up, glancing down at himself, ”Do I look okay..?” Yamaguchi thought to himself, he shook his head slightly, following Tsukki out of his room, he followed Tuskki outside and to the car that pulled up, Tsukki mom was already outside, helping get luggage out of the car, she glanced at Tsukki and Yamaguchi, “Boys! Do you mind helping instead of just standing there!?” She ordered, Tsukki and Yamaguchi (mostly Tsukki) helped get luggage out of the back of the car, “How much shit did you pack!?” Tsukki shouted. “I barely even packed anything!” said a voice from inside the car.
Yamaguchi's eyebrow raised slightly, he glanced at Tsukki for confirmation, basically asking “is that your cousin?” without saying it out loud, Tsukki nodded and huffed, continuing to pull luggage out. The car shook slightly as the passenger door opened…and wow, a tall figure stepped out, was that Tsukkis cousin..? It had to be, they looked so alike!
“Damn, did you get taller, jerkface?” the person said, “I told you to stop calling me that you little shitface.” Tsukki grimaced.
“Kei! Don't call your cousin that! Same goes for you y/n!” Tsukki's mom yelled, that was his cousin's name, y/n?
“Whatever..” y/n mumbled under their breath, they closed the car door and glanced around for a moment, their eyes landing on Yamaguchi. They held eye contact for a second before Yamaguchi darted his eyes away, cheeks flushing with a soft pink.
Tsukki noticed and his eyebrows furrowed, “No,” He said looking straight at Yamaguchi, He shoved a bag into Yamaguchi's arms, “Take this into the guest room.” He said, glaring slightly at Yamaguchi's flushed cheeks.
Yamaguchi walked into the house and into the guest room, trying and falling to take Tsukki's cousin off his mind. They were…pretty? Handsome? Cute? They were everything!
Y/n glanced at Tsukki, “What's up with your friend, he looks like a strawberry” Y/n grinned, holding back a giggle.
"He's weird, just leave him alone.” Tsukki said, grabbing luggage and pulling it towards the front door.
“Eh, he seems kinda cute, maybe he was flustered from how goodlooking I am.” Y/n teased.
“I doubt it was that, you look hideous.” Tsukki snorted, pushing his glasses up slightly, "You're saying that as if we aren't related!” y/n shouted.
A bit passed and y/n was officially settled in, Tsukki and Yamaguchi were back in Tsukki’s bedroom. Yamaguchi was a bit unfocused, his eyes kept darting to Tsukki’s open bedroom door and to his cousin's half open door, peeking in slightly from a distance.
"They're off limits.” Tsukki said bluntly, out of nowhere!
“W-What! W-What're you talking about!?” Yamaguchi stuttered out. “My cousin is off limits, understood?” Tsukki repeated. “I wasn't even thinking about making a move on your cousin!” Yamaguchi said back, defensive much. “Sure..” Tsukki grumbled, there was a soft shout from the kitchen.
“Kids! Dinner is done!” Tsukki's mom said, “C’mon.” Tsukki said, getting up and walking out of the room, without waiting for Yamaguchi, He scrambled up off his feet and chased Tsukki down the hallway, him and Tsukki sat down at the table. Y/n came down a minute later, soft steps that walked around the table and took the empty seat, directly across from Yamaguchi. Yamaguchi kept his eyes on his own plate, not even daring to glance up, not risking the chance of accidentally looking into those perfect eyes..SNAP OUT OF IT YAMAGUCHI!
Tsukki's mom noticed the silence and glanced at tsukki and Yamaguchi, “Say, how about you boys have a sleepover tonight? And in the morning you can show y/n around town.” She offered,
“Sure I guess.” Tsukki said, “Yeah, yeah that sounds fun!” Yamaguchi said, eating a bit faster, he gets to spend the day with y/n tomorrow? That sounds like heaven! He finished his food quickly and got up, bringing his plate to the sink and rinsing it, Tsukki got up after him and did the same, whispering in his ear "Don't act too excited.” With no teasing or joking visible in his speech, Yamaguchi swallowed quietly, nodding slowly.
“Alright, me and Yamaguchi are gonna head to bed, see you guys in the morning,” Tsukki said, “Goodnight..” Yamaguchi muttered, and they walked down the hallway and back to Tsukki’s room. They changed into their pajamas and Yamaguchi set up a futon on the floor, lying down on it, staring at Tsukki's ceiling. “Try not to think too hard.” Tsukki mumbled, taking off his glasses and setting them on his nightstand.
“Yeah..I won't." Yamaguchi replied, turning on his side, Tsukki shifted in his bed slightly before finding a comfortable position.
Yamaguchi tried to fall asleep, the thoughts of y/n came flooding into his mind.
But maybe he needed to think of them to fall asleep, because he did fall asleep, not when he was thinking of nothing, but when he was thinking of Y/n.
