Mary Stayed Out All Night (Korean: 매리 는 외박 중; lit. Marry Me, Mary! ) is a 2010 Korean romantic comedy drama, starring Moon Geun-young, Jang Keun-suk, Kim Jae- wook and Kim Hyo-jin. It is based on the webtoon Daum of the same name by Won Soo-yeon.
Mary Stayed Out All Night tells about Wi Mae Ri who is the pragmatic, cheerful daughter of a failed businessman who often tries to escape from debtors. She looks like her deceased mother, but her short-tempered temper comes from her erratic father (Park Sang-myun). Her father's business failures were always troubling, but Mae-ri still loved him. Because she could not afford the university fees, she temporarily stopped college, and without any special skills, started doing odd jobs. One day, while driving a friend to do one of those jobs, she accidentally meets musician Kang Mu-gyul (Jang Keun-suk) and after a series of events, they become friends. Mae-ri's father suggests she marry the son of his rich friend Byun Jung-in (Kim Jae-wook) to pay off the debt. She declined; when her father disallows her, and the fact is to forge the couple's signature on the marriage certificate, she pretends to be married to Mu-gyul. Instead of accepting that, her father proposes an agreement: spend 100 days with both of them and after that, she can decide who she wants to marry. And from there, a love triangle formed ...
