Hi hi! The main character does not end up having the option to use pronouns other than she/hers in the duration of the game. She questions her gender in one route, but doesn't reach a conclusion where she changes her pronouns. I'm also linking this comment from earlier for a more detailed answer: https://itch.io/post/10240453
Thanks for checking out the game! Even if you don't end up playing it, I'm glad you're here.
