A student named Matsubara Ryoji resided alone but had an uncle living nearby. Although he was busy and frequently absent, Ryoji was responsible for taking care of his wife and daughter when they were not home. Conversely, Ryoji harbored secret feelings for the aunt, Kasumi. Tragically, their neighboring homes were burglarized while they were away. In response, the uncle suggested that Ryoji move in with them to provide additional security.
