Bomi is a friendly broadcasting writer. She has a boyfriend named Jeong-nam who just graduated from law school, but they're not on very good terms right now. Their sex isn't fun either.

Man 1,2 and 3 and woman 1,2 and 3 check each other out but jealousy gets the best of them and they step over the line.
