I think this was the moment where this manga lost a lot of respect for me.
There is just something funny about a guy turning into a girl.
There is something truly sad and tragic about a perfect girl turning into a guy.
And the MC here truly lost respect because the girl had to do it for him. It's kind of an allegory for a male having sexual dysfunction... which is kind of sad too.
I don't know. When I saw that this was the route, I stopped caring about the MC.
