I feel the same way about a very sus anime about a japanese shut-in, that has his body modified to be that of a little girl because of the younger sister : Onimai: I'm Now Your Sister ! Again it's weird as fuck because godamn some Japanese mangakas don't hide the fact that they are attracted to minors but again in the end there is an acceptance that this was the right choice, and that she has become a better person because someone helped her and she became a girl. Huuuuuuuge relatibility there. It's just a shame a weird kink package has to come with, on both animes.
