A middle-aged man and a woman with black hair are on a date in the park under a gentle sun. What begins from there is a genuine SM training document. "I will immediately fall ill if you do not train me, Master. My body exists only for you, Master. Please enjoy it. Please do not abandon this female slave, Maiko..." Soon, the heavily trained melancholic girl fulfills her self-destructive desires through hardcore SM, sinking deeper into masochism, beyond any hope of redemption. #YoroP
