Dr. Kaguraoka, Mikoto's late father
"it was only based on his own experience"
So the ending was effectively a return to status quo. A non-ending, except now Mikoto is a bit less of an asshole than he used to be, I guess partly after getting a taste of what it's like to be a girl... in a manga with trashy attempted rape cliches. Did we really need to have a scene where some fuckboy gropes her "honkers" and put his hand down her pants? It would be at least a bit amusing if Mikoto's male bits came back before that just so the prick could get a nasty surprise before he gets clocked out.
I don't have anything against Mikoto becoming a boy again, but man barely anything changed from chapter 1 - not even the romance was resolved. I can't believe I started reading this in 2017 and only finished it now. Off the the completed pile with you.
