MRSS-125 Mahiro Ichiki looks into the smartphone of his wife, who would never cheat on her, and discovers that she is having extramarital sex with a hairdresser.

When I casually looked at my smartphone, my wife was being eaten by a hairdresser. - Apparently he invited me to dinner after saying he would consult with me, and then I went straight to the hotel, drunk. - At first, my wife, who had no intention of doing so, was aggressive and said, ``I will sue him.'' - However, as she reads the conversation history, her heart gradually becomes swayed by the shitty man. - Finally, the wife invites the man to embrace her. - Moreover, right after having sex with me... - Maybe I would have been happier if I hadn't seen something like this.
