Heeseung as your cocky roommate, he always cracks cocky jokes.

One night you were at the living room, doing your homeworks while he was in the kitchen, cooking dinner for you both bc you asked him to. After sometime he walked up to you then spoke in teasing tone, pointing out something pervy.

"your stomach must be really hungry, right? Your stomach must need some relief~... I bet you'll feel so much better if i filled you up right now~..." he let out the most cocky smirk ever.
