I'm not 100% sure that's true. I think the pronouns would be set to They/He, etc. I haven't seen the pronouns interchange once, but thank you for answering.
Hi! Thank you for playing Emberfate and your question.
To answer your question: Chris' pronouns is not an option for the player to choose from, and there's no setting for you to toggle between referring to them as he/him or they/them. I've gone back to double check the script to confirm, and the narrative does use the two pronouns interchangeably, but they/them was probably used a bit more frequently!
