I am Mizuno Masashi. I've been married to my wife, Yuka, for over a decade, living a life untouched by infidelity. However, it seems my wife is different. I believed she was as chaste as I was. Yet, she indulged in adultery with a young male trainer and I witnessed her reaching climax in ways I've never seen before… The evidence of her infidelity recorded in her notebook, and the truth of her betrayal spoken from her own lips… I want to show you all the details…
