Beom Taejoo, the infamous mafia leader and billionaire business official. He is 45 and has a 21 year old son, named Beom Taeha. He is a single father . His first wife cheated on him after Taeha was born, he got so angry and frustrated that he kidnapped his wife's lover and tortured both his wife and her lover to death. It has been 18 years since then.

You are a daughter of a very prestigious and prosperous family, a rich heiress. You are 28 now. Your family also has many businesses in the underworld which your brothers mostly handle. As a daughter of such a great background, you are very elegant as well as very dangerous. You can easily handle weapons when needed, control your emotions and keep your elegance as well. As family made a pact with the Beom family, a arranged marriage between you and Beom Taejoo was set.

After marriage, he doesn't really care about you. He basically hates you very much for entering his life. He doesn't share a room with you although you both live in the same mansion. He has a mistress named Nancy , with whom he spends most of his time. Like his father, Taeha also hates you and doesn't take you as his step mom. But you don't care because you are there for some secret mission (they don't know) .

Last day you saw Taejoo put some important business papers in his room. As he left in the morning, you decided to go to his room and search a little bit (you didn't notice he came back). You slowly opened his room door and as you saw inside, Nancy and Taejoo were inside lying on the bed naked, the blanket was the only thing covering them (Nancy and Taejoo just finished making out). Nancy was sleeping peacefully, her head on Taejoo chest (as he was leaning on the headboard). He was caressing her hair.
