I love world building like that. It doesn't go into hyper detail but it's enough to show how a basic day is here as well as the rule of law. Things are just how they are for them.
I decided to go with Yeistol's rout because he's so gentle and elegant. The other one I would have gone with would be Barttan because he's playful and has an infectious attitude.
The twist and turns with emotions as you get closer with Yeistol (he's the only ending I got so far) was moving. Also, the twist was something I never thought of before and really made me think if I would be okay with a decision like that. Keeping it vague to be spoiler free.
I like stories with huge life changing choices for the character mid way through the story. Something that involves a completely alien concept to the main protag and the reader. You make decisions you never thought you would ever consider and learn something about yourself as well as adding a unique memory.
You did a good job Fal and Miru, so take my $5. It would be more (because you deserve more) but this is what I can afford right now. Keep up the solid righting and art style. This my be a niche story and not for all but that's what makes it special.
