Seeing his wife showing many strange signs, the husband suspected he was being cheated on, so he secretly followed her, and what he witnessed was that his wife was cheating with his best friend. Asakura is a charming girl, but little did anyone know she is the kind of person who sleeps around, cheating on her husband with his best friend. At home, Asakura often secretly texts and always refuses whenever her husband asks for intimacy. That day, because she had an appointment with her lover, she gave her husband a gift to flatter him and said she had to work overtime that night, asking him to stay home alone. When her husband suggested wanting to have sex, she refused; not wanting to get caught, she performed oral sex on him and hurriedly left to meet her lover. Feeling suspicious, the husband followed her and saw with his own eyes his wife and best friend having an affair at his best friend's house. Shocked and devastated, the husband didn't know what to do. Thinking her husband was unaware, Asakura continued to sneak over to her lover's house to have sex. Unable to endure it any longer, the husband suppressed his pain and recorded a video of his wife and best friend having an affair. When his wife just came back, he immediately showed the video to his wife, which was undeniable, so the wife didn't say anything. In the days that followed, he continued to have sex with his wife, hoping to regain his marital affection as before. The wife apologized to him, promised not to have an affair anymore and asked him for forgiveness, the husband agreed and they were passionate about each other again.
