Satomi (31), a married woman, feels subtle unease in her daily life with her husband, unable to forget the man with whom she once spent a night during a shoot. Every summer, memories of him resurface. He holds a special place in her heart, and the experience they shared during that past filming lingers deeply within her. Torn between desire and guilt, she waits anxiously for contact from him—part of a one-time-only reunion project—uncertain whether she truly wants him to come or not. In searching for him, she's also searching for an answer to what marriage really means.
