That M housewife infidelity training series is back!! The housewife, Kana, who looks docile and clear, doesn't seem like she would have an affair. In real life, this housewife dedicates herself to her family, but she is not treated as an equal by her husband and is left with unfulfilled desires. She spent her time peeking at SM-related smartphone sites to relieve her uneasy feelings, but out of a light-hearted mood, she registered on a dating site, was aggressively approached by men, and before she knew it, she was being trained.
