Very intriguing so far! I'm a massive simp for Arden, they're so cute and I'd give them the world. I like that they have their own unique communication style with MC. Yanking Cassius around was fun too, I only wish the kiss scene had a 'dominant' option-- after choosing every dom option up to that point, it felt a little disappointing to have my MC suddenly act all passive and let Cassius take the reins.
The plot itself is interesting and I'm curious about how it will resolve. I'd like more chances to see details about the MC's history and religion and just generally more worldbuilding/backstory, it seems like there's a lot going on and the reader is much less informed than the characters.
