7 years of marriage. Katsu and Mina (Shiraishi), who are often away from home on business trips, are leading different lives. Such Mina's pleasure is a moment of chat with her nephew Masanobu. I didn't have any special feelings for Masanobu, who often visited my house because my house was close. One afternoon, Masanobu happens to see Mina walking around the living room wearing only a towel to drink beer after taking a bath. Mina's little devilish feeling aches for Masanobu who can't hide his excitement.
