University student Ryoji Matsubara lives alone but frequently visits his uncle's nearby home. With his uncle often away due to work, Ryoji becomes a dependable figure for his aunt, Kasumi, and her daughter. Privately, however, Ryoji harbors a secret longing for Kasumi.

When a robbery strikes the neighborhood, Ryoji's uncle suggests a solution: that Ryoji move out of his apartment and come live with them under one roof. This new living arrangement brings Ryoji's hidden desires dangerously close to the surface, setting the stage for a tense and intimate conflict.
