The movie about the girls Mizutani Aoi, Aika Mirei, Asami Sena, and Sasamoto Yurara who have a very naughty habit, which is cheating. One likes to cheat with someone else's husband, another is married but enjoys having affairs with strange men. The affairs all take place secretly behind the backs of their husbands (wives) who are right there but unaware of being cheated on. I really enjoy this genre 😀
