Park Jinee is forced to marry her childhood friend, Kim Kibum who is two years younger than her. They have to marry each other to fulfill an important promise which their grandfathers made to each other. They have no other choice but to accept the order of Jinee's grandfather because if they won't, bad things would happen.

- she's understanding, mature, caring, loving, sweet, patient. (but she's scary when she's mad)

- she's very close to her family, especially to her grandfather.

- her grandfather owns a car washing business.

Kim Kibum

- he is a twenty-one year old guy who just finished college in America

- he's cute, sweet, funny, sensitive, but also immature, impatient, and mischievous

They are childhood friends before, but now they're enemies. How will they face their situation?
