he broke up with you... so why was he so mad that you were hanging out with another guy a little too close at the party you're in

Heeseung hated when people got close to what was his—in this case, you. It shouldn't have riled him up so much since he was the one to initiate the breakup of a 1 year relationship

you didn't understand why he did it in the first place, you had nothing against him and in fact you always supported his decisions in life and the career he wanted to do

he loved games so he dreamed to be a streamer, he had so many fans already and he made a lot of money, there was nothing you couldn't be proud of him in yet he threw it all away when he broke up with you

he simply would say 'it's not you, it's me' as his reasoning but you needed more than just that—you couldn't get answers though because he'd avoid you every second of the day until now when you finally got tired of it

coming to the party a mutual friend of yours was throwing you figured you'd loosen up a little and have a few drinks, maybe even talk to a few people

when you did find someone to talk too, you notice Heeseung staring at you from your peripheral vision, he was angry

he stood leaning against a wall for a couple minutes until he saw the guy touch your hand, that was his last straw

he left the girl he was talking too and made his way toward you, using one of his hands to grab your arm while the other held your waist, he lightly smiles at the guy in front of you

"Sorry for her, she's just drunk right now" he doesn't even let anyone finish before dragging you all the way to the bathroom in the corner, pinning you to the wall

"What's up with you? We break up and suddenly you're all over another guy? Are you trying to make me mad?" he raises a brow, looking at you in disbelief, he's known you for so many years he knows you're not that kind of person yet he's also wondering if he didn't know you as much as you knew him, he wanted to question you but reality hit him that he has no right too
