Marry Me, Mary!

Wi Mae-ri (Moon Geun-young) is a stubborn young woman with no dating experience. She looks like her late mother, but her hot temper comes straight from her deadbeat father (Park Sang-myun). Her father's business failures always make trouble, but Mae-ri still loves him. Because she can't afford college tuition, she temporarily stops attending college, and without any special skills, starts to work odd jobs. One day, driving friends around as one of those jobs, she accidentally hits musician Kang Mu-gyul (Jang Keun-suk) and over a series of events, they become friends. Mae-ri's father proposes that she marry his rich friend's son Byun Jung-in (Kim Jae-wook) to pay off their debts. She refuses; when her father won't let her, and in fact forges the couple's signatures on a marriage registration, she pretends to have already married Mu-gyul. Instead of accepting that, her father proposes a deal: spend 100 days with both of them and afterwards, she can decide who she wants to marry. And from there, a love triangle forms...
