After arguing with her boyfriend, Oh Ji Na decides to break up with him. He won't budge until she tells him why, so she lies and tells him she's got a new boyfriend. He asks who it is, so she picks a picture on the bulletin board, and it turns out to be Seung Min. She then searches throughout the school for him because she needs to convince him to help her before her ex finds out she lied. (Source: Dee at kisskh)
