Karin Oriyama is a first-year high school student who has spent her entire life living in luxury and being spoiled by her father. She sets her sights on Nao Tsurugi, a popular third-year student at her school, and believes him to be the perfect candidate for her boyfriend. On her 16th birthday, Karin's father suddenly announces that she will be wed to Nao, who she had been secretly betrothed to since birth. Overjoyed with the news, Karin and Nao marry and move into a run-down apartment building to spend their newlywed life. To Karin's surprise, however, Nao confesses that he agreed to the marriage for financial independence, and he wants nothing to do with her. He proposes several rules for their co-habitance: they must not mention they are married at school; they must cook and clean after themselves; they must not enter each other's rooms; and they are allowed to date other people. Karin is crushed by the reality of her marriage, but she must overcome her ego and become more self-sufficient to earn Nao's respect.
