<<Son Chaeyoung is a daughter of a famous CEO but she never reveal her true identity to anyone except for people that are close to her. She's a cold type and arrogant kind of kid. She has no interest in relationship and she thinks that it's a waste of time.>>

Minatozaki Sana- troublemaker by day, a cheating gambler by night. Take note, a sexy motherfucker. Sana just really loves to get into the nerves of the Vice President of their department, Park Jihyo. Jihyo's a smart, pretty, responsible, to die for girl. Literally the girl of every man's dream. She might look intimidatinh but she's a little bit TOO nice. 'A disaster' is what they are.
