My Sassy Girl Collection

Based on a series of true stories posted by Ho-sik Kim on the Internet describing his relationship with his girlfriend. These were later transformed into a best-selling book and the movie follows the book closely. It describes the meeting of Kyun-woo (Cha) and an unnamed girl. Kyun-woo is shamed into assisting the girl because the other passengers mistakenly think she is his girlfriend. Once he helps her, Kyun-woo develops a deep sense of responsibility for her which enables him to tolerate (somehow) the girl's abuses.

Gyun-Woo (Cha Tae-Hyun), who can't forget the sassy girl, meets his first love (Victoria). He fell in love with her when they were in elementary school. At the time, other kids teased her because she wasn't very good with Korean. Despite the opposition of others, Gyun-Woo and his first love marry. What awaits for Gyun-Woo goes beyond his imagination.
