Oh, this one, I remember reading this years and years back and being super confused on how someone never felt gender dysphoria their entire life and then suddenly felt it after like, some time in an isekai. And looking at it now, it might not even be real so it feels more and more strange to me because I can't comprehend how someone would be comfortable for so long and then suddenly uncomfortable.
Well whatever, I don't have gender dysphoria so maybe this is normal for people that do.
