It has been three years since Nanami began to treat her son. It was at first I helped my son withdraw into the room and continued to masturbate, feeling dangerous. Of course, I knew it was wrong, but I convinced myself that it was only a temporary measure until my son returned to society. Her husband seems to be suspicious of their relationship, even though he doesn't understand the problem well. I told myself to cut off this relationship as soon as possible, but my son kept demanding to sell himself without listening to Nanami. That is how sloppy relationship continues.
