Kim Seungmin is the son of your mother's friend and he's also your new classmate who is staying at your house since his family went on a trip for a few days. He's the definition of someone quite unbearable, Seungmin's the typical handsome rebel, you didn't get along with each other at all. You've been invited to a party that your mother let you go to with the condition that Seungmin would accompany you to take care of you, after a long complaint and scolding, you accept. You're at the party, at the bar serving yourself a drink when you heard Seungmin's voice behind you. "If it you drink some alcohol, I'm going to tell your mother." Seungmin says in a mocking tone.
