I'm waiting for Talia to be a. romanceable. character. There is absolutely no way it's a coincidence that she gets excited to learn Grey is into women (and honestly I wouldn't mind more female content)
Honestly I don't think there needs to be a 3rd in their situation cuz unlike with Simone, there are no woman likers besides Gray in Gabe's route. I would be fine with just Gray and Talia, like the scene in Mark's route with Simone and Gray in the bathroom. With how the story's going after the most recent update, I have no guesses besides like idk horny spell casted during their DND isekai arc, but stranger things have happened in this game.
