Wife exchange / embarrassing madness

Even though she is a new wife, her husband Yosuke and Narimi are reluctant to have sex. One day, Yosuke witnesses an executive and a secretary's dance in place of the hotel. From the dance of having sex with her, she was told that "a woman has a concubine and a prostitute's face," and Yosuke retreated without courage. Narimi, who used to be fishing for men in Teresa, now had a relationship with Yosuke's boss Tajima. Narimi, who was held by him, was the face of a prostitute. Yosuke finds contraceptives and flashy underwear in Narimi's room, causing suspicion. Narimi tries to cut off his relationship with Tajima, but his actions escalate.
