屋根部屋のネコ (2003)

Kyung Min, a law student, is in desperate straits, so he decides to take it upon himself to help Hye Ryun's poor friend, Jung Eun. This is the beginning of an extremely volatile friendship that somehow ends with the two of them living together under one roof, or to be more specific, living in a room on top of the roof of an old building. Kyung Min's bratty ways clashes with Jung Eun's simple living, as he steadily takes advantage of her kindness and good nature.
