I've barely even begun, I'm just setting up my character but allow me to share a little reaction of mine
Me: Mmmm sister. No, you know what, sibling. yes, they/them. Awesome. Lesgo.
Later
Leo: that one is (insert pronouns)
Me: Wait...
Me: (cautiously clicks through pronouns)
Me: Oh my gosh... you can be a sister AND have they/them pronouns?!
Me: (big fist pump) YESS!!! DREAM COME TRUE, GENDER EUPHORIA, YES!!
BRB, going to set up the nonbinary sister and save their sibling. Thank you so much for including this :)
