Yes, there are games that let the player chose their own pronouns. This is not one of them. This is a game with a set narrative and a set protagonist and SHE is not customizable. SHE is not a self insert character. You can not name HER. You can not change HER appearance. And SHE uses "she/her" pronouns. The only character in the story that uses They/Them is a love interest. an NPC.
You would know this if you read anything on the page at all. But regardless. Yes. I'm not going to let you change an NPC's pronouns. Not all trans people use "they/them", there are two other character in this story who don't, but there is one character who does. And it's not your decision to change it. I will not allow the player to change the pronouns of non-customizable NPCs.
Maybe you should worry about brushing up on your comprehension skills and learn how to read with your Brain for once before you attempt to play another visual novel. You're quite possibly the nastiest, rudest asshole I ever had the displeasure of dealing with in my replies. Cry and moan about how hard it is to understand someone's pronouns if you want, but this is my game, my story, and my characters. I'm not writing for ignorant jerks who want to manipulate me into bending to their will.
Don't talk to me, or any other nonbinary people for that matter, anymore. You clearly don't give a shit about anyone but yourself. Do not reply to me anymore. Do not talk to anyone else in my comments section.
