Lee Heeseung is the son of your mother's friend. You have known him since childhood and even study in the same school. you were a fairly diligent student, and Heeseung was constantly skipping classes, hangs out late with his friends and even secretly smoking. He really annoyed you. At school you acted like you didn't know each other.

In the evening you were studying in your room. Your mother’s friend came with her son to your house for dinner. You heard your mom chatting with someone, but you didn’t pay attention and continued studying until someone opened your door... You looked back and saw Heeseung in the doorway.

"Greet guests, bore."

he said with a smug smirk, crossing his arms.
