Hmm...Again, this felt somewhat milder than most things in this magazine.
I mean, you know, at least he got some and seems to be living a somewhat decent life for someone sold into prostitution.
Despite all that happened, I think that his love for Miss Izumi was reciprocated to...some extent, but maybe not in the way he liked her. I mean, she actually left him money after she went with the guy, presumably for him to finally leave and live a life of his own.
Instead he stayed and decided to become her daughter's plaything after continuing his indulgence with the other prostitutes. Oh well, at least he seems content with his life.
His mistress left and gave him money (and most probably his freedom), but he decided to stay and serve her daughter (who looks like him now that I took a better look at her)...
