Synopsis

Kimi is married to Tatsuro, who has a son, Kengo, who is the same age as her. Every night, Kengo can hear Kimi's moans coming from the bedroom, but he somehow manages to keep his sanity. Meanwhile, Kimi's childhood friend, Kaori, runs away from home after a marital quarrel and comes to stay with her. Kaori realizes Kengo's feelings... The director is Takehora Tetsuya, whose style is often light and erotic comedy. Yuki Misa, who exudes a sparkling and seductive charm, plays a stepmother who wants to cherish her family. The agony of a single man in his 30s is entertaining.
