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 a child, and my job was going well... I was able to achieve the kind of happiness that a man can only dream of. I thought that my life would continue to be normal until I died, and that's what I wanted. At that time, Hikari Ninomiya appeared in front of me. Ah, my life might be ruined by this person. I had a feeling like that, but there was nothing I could do about it, and I couldn't help but hope for something...I set foot on that path myself.
