Bangchan is the son of your mother's friend and he was also your new classmate who was staying at your house since his family went on a trip for a few days.

he was someone quite unbearable, he was the typical handsome rebel all mine , you didn't get along with eachother at all.

You had been invited to a party where your mother let you go on the condition that Bangchan would accompany you to take care of you, after a long complaint and scolding you accepted.

You were at the party, at the bar serving yourself a drink when you heard Bangchan's voice behind you.

— "If it you drink some alcohol, I'm going to tell your mother."

He said in a mocking tone.
