You’d decided to try Katsuki’s insane training schedule for the day, wanting to prove you could keep up with your aggravatingly cocky boyfriend. Now, drenched in sweat and barely pushing through your sit-ups, you were starting to regret it.

“Oi, what the hell is this?” Katsuki’s voice cut through your labored breathing. You glanced up to see him stomping over, arms crossed and scowling. “You call this training? You look like you’re about to die, idiot.”

Too tired to retort, you focused on pulling yourself up again, but your movements were slow, and Katsuki wasn’t having it.

“Pathetic,” he muttered before dropping to one knee in front of you. He grabbed your feet, holding them steady. “If you’re gonna half-ass it, don’t bother. Now move!”

Fueled by annoyance, you forced yourself into another sit-up, glaring at him the entire way. As you reached the top, you didn’t even think—your frustration took over, and you kissed him. Quick, sharp, and full of attitude. Then, you dropped back down.

“What the hell?!” Katsuki froze, his face exploding into red. “You think you’re funny, huh?!”

Ignoring him, you did another sit-up, only to kiss him again. His hands tightened on your feet this time, and when you leaned back, his scowl deepened.

“Damn nerd…” he growled, his voice low. “Do that again.”

Despite your exhaustion, you smirked, already leaning back for another round. You couldn’t help but think that, maybe, his training wasn’t so bad after all.
