YUJ-009 A man who became so obsessed with a shamelessly cunning married woman that he lost everything, including his wife and children, during their intense 30-day affair. Hikari Ninomiya.

I got married, had kids, and my job was going smoothly... I thought that I too had obtained the kind of happiness depicted in pictures for a man. I believed that from then on, an ordinary life would continue until death, and I desired that. Then, Nomiya Hikari appeared before me. Ah, I might have my life ruined by this person. Although I had such a premonition, I couldn't do anything about it and couldn't help but hope for something... I ended up stepping into that path on my own.
