I am Masashi Mizuno. I have been married to my wife, Yuka, for over a decade... We lived a life free from any scandalous behavior. However, it seems my wife was different. I believed, just like me, she was a virtuous woman. Yet, to see her lost in infidelity with a young trainer, reaching a climax in a way I've never seen before... The evidence of her adultery etched in her diary, and the truth of her betrayal revealed from her own lips... I want to show you all the details of this affair...
