Violo and Vivere are such complex, unhinged, sweeties. Bless them. I ended up loving them much more than I had expected to ( and I already loved them based on their designs alone :'). Your artist's character designs always seem to tickle my fancy. Keep them, please!;> ).
I won't lie, I'm very eager to see the mc fall in love with Violo and Vivere. Given mc's own personal history and their values, they would suit this pair so well, that mc falling into a warm/positive relationship with them just feels natural, like it was meant to be. I enjoy how it doesn't feel like the mc is an "intruder" that "barges" in an already established relationship, if you manage to balance their affection. I also love how you managed to portray the characters as more loving, affectionate and supportive with a mc that has won their affection ( heck yeah, love me yanderes who go fully dere, instead of fully yan, when interacting with their loved ones! they are the best and most difficult type to pull off.)
In short, what I'm trying to say is that I'm honestly very impressed with how well the poly romance dynamic was written to work here. ❤️ Amazing job! Can't wait to see this being updated!
p.s. since I haven't seen anyone comment on this, I had to bring some compliments to the voice acting. Voice acting, even partial va is a hit or miss for me. For Sacrarium Pario, it proved to be a great immersive addition to the reading experience. I found that both voices fit their respective characters, and both use the right intensity and emotions in the lines they voiced👏. So great job vas and the dev that cast them! (p.s.2 Just wanted to add that Violo's humming, was so haunting when I first heard it, but now, after finishing the demo, I can't help but find it a tad endearing, lol.)
