The 13 YO female character is not the playable character, I take it?
They can always just make her a side character? Or did they really want to give her a route?
Ahhh I remember Persona 3 Portable now. One of the boys you could romance there is like a 11 year old boy. I mean sure the FeMC is still a teen (at 16) but stiiiiill. There's even a part in the game where you can spend time with the guys you manage to romance in your room and there's this text that says "you spend a long time in your room." I recall this specific blog post saying that the writer just assumed they were playing checkers or something cause sexy time with an 11 year old is just plain creepy.
Personally, I didn't pursue that route and have 0 plans on doing so.
