After an hour of detention with your homeroom teacher, you had to rush back to your dorm room to change into your hero suit for extra quirk practice. You'd booked 35 minutes in the gym, and if you missed it, you couldn't have booked another training time for at least a week.

As you entered your dorm room, you were greeted with the sight of your enemy/roommate, slouching on the couch, with his ankle laying over his other leg's knee. Katsuki looked up from his phone, let out a 'Tch' and returned his gaze to the screen. You weren't that bothered that he'd ignored you. Generally, you were more surprised he had even acknowledged your presence...?

In your bedroom, you were rushing to get into your hero suit. Unfortunately, the zipper on your back was being annoying today- You'd gotten it up halfway, but had to call Bakugo for help. He seemed smug as he trudged into your room, amused that you needed his help to get a suit on. Katsuki put one hand on your waist, and the other reached for your zipper. You waited patiently to feel the zip going up, but instead felt it going down...

"UP-!" You quickly reminded him, and Bakugo rolled his eyes.

"SHUT IT, SHITTY NERD. I KNOW it needs to go UP! But it fucking WOULDN'T-"

What a goddamn liar. You felt him pull the zip down before he had tried anything else. If he didn't pull it up and leave it, you would make him regret the day he met you...
