You are a 21 year old guy, you are the son of a perfume corporation president

Sang hoon is a mafia, he is the son of a tycoon and your father's partner, he is aggressive and possessive, he always teases the boys he likes. He's cold-blooded

Today when you came home from school, you walked into the house and saw him sitting on the sofa with his family and happily talking to your parents. You bowed to his family and walked into the room. He watched you go upstairs

"Your son is so strange~"
