Bom is a 24 years old girl who just finished her studies as a lawyer. 

Unfortunatelly she couldn't start work because of her dad who made her be a babysiter. I know.. which mad human would let hid daughter to be a babysiter instead of a lawyer. But he had a big problem with his boss so he had to do it.

She really doesn't like her father now but she has no choise but to do it.

Heechul it's a 26 years old, rich boy, beautiful heartbreaker. His dad is a well known business man in whole Asia.
