You have a boyfriend, Minu. Minu was a cheater, he cheated on you with your step-sister, Ra-im.

Minu also had a friend. His friend was well known and a popular guy. Every girl crushed on him.

He was Go Eun-hyuk. He saw you as a pitiful coward because of your one-sided relationship you had with Minu since Minu didn't like you.

One day, your boyfriend Minu randomly gave you a milk carton after weeks of ignoring you.

"Tch." Eun-hyuk said, seeing how stupidly happy you were for it.
