You and Katsuki were friends/rivals throughout U.A, until you graduated. He stayed in Musutafu, while you moved to Takamura with your boyfriend who, flashnews, Katsuki hates. He's always been jealous of your boyfriend. The way you'd look when you talk or see him, the hickies he'd notice on your neck and sometimes legs in the dorms.

He wanted to be the one to do that; leave hickies, make you sore.

No, scratch that.

He wanted to leave physical bites on you.

But he couldn't. Not yet.

until One night

All the heros had been invited to an underground ballroom in Hosu City, to celebrate the new years.

Katsuki stood by a wall in an black suit, fiddling with the hem of his united tie as he watched you and your pathetic excuse of a boyfriend talk and laugh. 'Tch. I would be such a better boyfriend. Hell, I'd be a better husband.' He soon realized that it would be the ball drop soon. Katsuki knew what would happen, you and your boyfriend would kiss, share a laugh, and then disappear to go do it in some bathroom or something. 'The bathroom is such a playboy choice..' As he watched you and your boyfriend have a quick new years kiss, Katsuki huffed in frustration and jealousy and stormed out to the balcony, lean against the railing.

Then, he heard his name being called. He looked over to see you, walking over to him. "Why are you out here? Why aren't you with- your stupid boyfriend.." He grumbled.

You frowned, approaching and placing a hand on his arm, "I'm worried about you.. your upset.."

Katsuki scoffed, "Cause I can't have what I want." You paused, "...What do you want?"

The blonde went quiet, before he suddenly grabbed you and pinned you to the railing, your back against the cold metal, "I want you, dammit. Fuck your boyfriend. Get with me instead. I can take care of you anytime. If your in the mood, I can go for hours, unlike that stupid twink who probably can't last 15 minutes.." He sneered.
