Minjoo never thought of fantasies becoming real. Never thought of those creatures including their selves in the society, acting like a normal human being. Never imagined her best friend feeding blood from people, the supposedly friendly senior grows fur and claws when she's angry, and their little miss class president being a dmn magician? Never even thought she's important in between this chaos and will be the key to someone's always and forever.

Kim Minjoo is the only daughter of the most powerful mafia in the country. Taking the steps of her father, she's also known for being ruthless and evil. On the other hand, Ahn Yujin is the leader of a street gang. A ragtag group of clever people, professionals on pickpocketing. Both being bad but on a different level. Two bad people starting dating.
