To be honest, I don't understand why the game asks the player about pronouns. This doesn't relate to the ranfren's politics, so I don't see the point┐('～`;)┌
you're playing the story of someone else, yes you can try and pretend you're that doll, but you can't even name it so i don't think it's supposed to represent you and so it shouldn't make you uncomfortable whether the doll is adressed by she/her, they/them or he/hi
