Mischievous Kiss, a.k.a. Playful Kiss, is the Korean version of a Japanese manga that has been made into Japanese, Chinese, and Korean series. It is about a girl who falls in love with a genius in her school, then slowly forms a relationship with him after her family moves in with his after an earthquake destroys her new house. It is a charming romantic comedy, and I have also seen the Taiwanese version, It Started With a Kiss.
