Yeah, sorry. I think it can be cute when a guy turns into a girl. But it's downright creepy when a girl turns into a guy, especially if they're the ONLY one who changed and they were a rather cute/attractive person and not the MC (especially if the person who is the MC was already interested in them romantically). Call me a hypocrite. Unless the girl was already basically mannish, girl mannerisms just... don't work for guys. Especially girly physical affection, and a lot of facial expressions take on different meanings and perception depending on gender.
