Your upperclassman friend,his name is kim-taeyong,he is the most tsundere of the tsundere

And always being Denial to his feelings,he has a crush on you but he keep deny his feelings

You are talking to him,and you talk about a boy that you think he looks cute, suddenly he got angry,when you tease him that he likes you he pout

"Like you?! Pffftt,no,i rather kiss my friend's ass than liking you" but its really obvious that he is lying,he keep looking at you with heart eyes time to time
