I'd say that this manga is different from Boku Girl in the aspect that our MC was rather givin' implant suggestion throughout the story up until now and became a girl via surgery unlike in Boku Girl where as that one happen/cause by magic. In Boku Girl that MC wasn't givin' implant suggestion but rather comes to decisions "that" maybe this is better and he realise that as a she "he" love his friend.
This is quite the psychological one, that is what i think after re-reading the chapters and what makes me think that? if you have notice just about everyone say he looks girly not because of his body but his face, he lacks the necessary to look the part but his action aside. Everyone is just implanting the idea that he's better off admitting it especially the president who kept going on about it for as long as i remember.
Your thoughts?
