These days, companies will do anything to gain a monopoly, even go as far as to marry off their own daughter. Han Jihoon, the third heir to Han Enterprises has every intention of wiping his only competition, Kim Jihwan, out of the race. But there's two problems. Han Mira is the next heir to Han Enterprises and the highly-successful-until-this-point Kim Jongin is the heir to Kim Family Industries. A devious plot unfolds on the Han family side and Mira can sense the scheming in the air. 

Mira started out as a normal girl with a normal life and normal wishes, but all of that was turned upsidedown when her dreams to go to college were destoyed due to her mother's selfish needs; her needs for Mira to obliterate Kim Jihwan and absorb his company. Up until this point, Han Mira and Kim Jongin were raised to hate each other, but there's a turn of events that will soon change all of that, or will it? Han Jihoon has every intention of handing Han Mira over to Kim Jongin in exchange for the forfeit of Kim Family Industries, and the best part: Mira has no idea that her fate had been decided the day she was born. 

In a fiction of intense drama with heart-warming and heart-crushing scenes, an adventure though the heart of Kim Jongin and his struggle in appeasing both Han Jihoon and himself. It's becoming very hard to breathe.
