Recently, Eriko, a frustrated married woman who is not satisfied with her husband's work, complains about her neighbor's friend Marina, Yuu. The two, who are free from stress, warn him, "If you don't do that, you'll wither away as a woman." Feeling uneasy, Eriko asked how they relieved their frustration, and it is said that they are venting by having sex with men other than their husbands! Eriko is surprised by her friends' cheating, but she also envy her unrestrained sex life.
