ok so i got an idea. how about matsukawa getting kind of mad bc reader flirts with makki even tho mattsun gave obvious hints :3 hope you understand it muah love u 🤍
Matsukawa was not the type to blow up.
He kept a level head, didn’t make much trouble for his team, he was overall pleasant.
So why the fUCK was he about to explode and blow chunks all over the gym?
“Your jersey looks like it’s fitting you tighter now! You been working out?”
Steam practically seeped from Mattsun’s ears as he watched (Y/n) shamelessly flirting with Makki. What’s worse was he was flirting back!
“Oh you noticed?” Makki teased, playfully flexing. “You been checking me out, (Y/n)?”
Mattsun didn’t know what he did wrong. He was more than obvious when it came to flirting with (Y/n), but all she ever did was turn away or hide from him.
Dammit, maybe he was too forward? Or not forward enough? No way, if he were anymore forward he would be making out with her in front of everyone! GOD!
“Mattsun! It’s your serve!” Oikawa called, pulling Mattsun from his thoughts.
He growled to himself, adjusting the practice jersey that clung to his arms. He had been working out too... not like (Y/n) would ever notice.
Mattsun served the ball, huffing as it flew over the net and landed just outside of the court. The ball had made that satisfying SMACK, but that wasn’t enough to calm Mattsun down.
Oikawa approached him, gingerly placing a hand on his shoulder and offering him a small smile. “Why don’t you take a break from drills, huh...?”
Mattsun slowly nodded before walking off the court towards the bleachers.
After a couple minutes of sulking, (Y/n) sat beside him and lightly bumped her elbow against his.
“Someone woke up on the wrong side of the bed. What’s got you worked up?” she asked, batting her eyes at him.
“Nothing.”
(Y/n)’s lip jutted out into a pout. “It’s not nothiiing. You’re upset.”
“I’m not upset.”
“You’re wasting your time, (Y/n),” he huffed, “why don’t you go back to Makki? He’s much more conversational than I am at the moment...”
(Y/n) blinked, lightly gripping her clipboard. “Are you... Are you jealous?”
Mattsun’s cheeks went red. He was caught.
“N-No! Jealous? Me? Never. What you and Makki do is your business. It’s not like I like you or anything, stop assuming things.”
That word-vomit definitely sealed the deal.
“You are! You so totally are!” (Y/n) laughed, lightly bumping him again.
He didn’t want to admit it, but her laughter brought a small smile to his face.
“You want to looooove me! You want to huuuug me! You want to kiiiiiss me-”
“Took you long enough to realize it.” Mattsun interrupted her singing. He smirked when he saw her jaw drop.
“Wha-really?!” (Y/n) squealed, holding her clipboard over the lower half of her face.
“Did... you really not realize I was flirting with you?” he asked, raising an eyebrow at her.
“N-no! I thought you were joking!”
“Well you never laughed...”
“Cause you’re not funny!” she whined, blushing darkly.
Mattsun narrowed his eyes at her, studying her for a moment before smiling. “You knew... you’re just shy...”
(Y/n) gripped the clipboard so hard, Mattsun thought it might snap in half. “I-I am not! I’m-”
Mattsun gave her cheek a quick peck, shutting her up. “Then lets get some ramen after practice... unless you’re too shy or too busy with Makki.”
(Y/n) gulped and slowly lowered the clipboard onto her lap. “Fine... you’re covering me though.
“Of course, this is a date after all.” He winked, standing up and making his way to the court.
He had the biggest, cheesiest smile on his face, one he wouldn’t let (Y/n) see. Especially since he had been so smooth about asking her out. Little did he know, she had a matching smile on her face as well.
