I'm not even sure if the hero is actually transgender. Sure, (s)he wants to be a girl, but it does not mean that he wants to identify himself as a girl as it is purely his fetish, and he merely accepts his fate. If you ask me whether I want to change my biological sex to female then obviously yes I have a fetish for lesbian sex (in here, who isn't?) but I would not identify myself as one, duh. Heck, being a futa might be even better.
I'm probably wrong because english isn't my first language, but is this what the kids call a "hot take"?
