Next movie in my must-see list

My Boyfriend is Type B

He's (Lee Dong-Geon) the type of guy who leaves his girlfriend in his car so that he doesn't have to pay the on-street parking fee. His idea of a gift is a walkie-talkie set, so he can reach her at his convenience as quickly as possible. He shops for what he wants first, but makes her pay. Then he drives her crazy by asking her ever so innocently, "Should we break it off, then?" He might be a jerk, and she might be a patsy for staying with him. But that's because he has blood type B and she's type A, according to Chae-yeong (Shin-Hee), a dating consultant in the movie My Boyfriend is Type-B.

A strong believer in the blood type theory, which says that one's blood type determines one's personality, Chae-yeong goes on with her wacky logic about how blood type can have an effect on a person's love life. Her point is that a type-B male is conceited, stubborn and absolutely useless as a boyfriend, especially when the female is timid and obedient, like Ha-Mi (Han Ji-hye), who has blood type A.
