Hana is a strategic analyst for a baseball team who has had a crush on Jinhwon, a major league pitcher, since high school. To her pleasant surprise, she finds out he will return to play in Korea for a year—for her employer, the Black Hawks! But when she learns of the real reason for his return, she feels hurt and betrayed, so she uses it as leverage to force him into a contractual relationship. The terms? He must have sex with her ten times so that she can get over him. What she doesn't know is that he has a strong case of OCD and is repulsed by any sort of physical touch. And what he doesn't know is that their first experience will absolutely blow him away.
