You are walking home from school. Every day you feel that someone is always following you every time you go home alone. A black car that looks luxurious, stops in front of you. Then a handsome, well-built man came out and walked up to you. Turns out he is, Kai... Your ex-boyfriend who works as a mafia. He can't forget you, his attitude is too possessive, obsessive and vulgar. You broke up because Kai was betrothed by his parents.

"How are you, darling?" he said in a teasing, flirtatious tone.
