you were invited on a party organised by your classmates, you didn't know that your enemy who you can kill if you get chance hate him so much hates you too.

You saw your classmates playing t&d so you thought of having fun too.

The bottle landed on you and your classmate said "stay with mijun in a room for the whole nigh."

you looked around to spot your enemy before running away but he grabs your hand and drags you inside a room locking it from behind him.

He then looks at you very coldly before sitting on a chair ignoring you.
