Huh?okay but how'd we end up 13 chapters ahead?
her previous husband died of exhaustionJEBUS MOM IS THAT HOW YOU GOT HARU? SLIP IN SOME APHRODISIAC???
I was about to suggest the same, except not as a joke or shitpost. I find the only actual explanation possible being that the mother drugged him with a detective conan pill when they ate curry one day. Because I don't see who else has both means and motive.My joke shitpost theory is that the mom is the one who turned him into a girl in the first place somehow.(maybe magic, or some weird medicine, etc)
A previous chap showed the mom already shipping lil bro even before he was a girl.
