I don't know what's so egregious about nanao, she meet asumí normally, they have shares interests and fell for asumí not based on her look but the time they spent together.
Like I get that the steamy often kinky sex is great and all but watching thier relationship slowly evolve while opening to each other and also fucking is just as great if not better in my opinion
I also like jealous nanao...
I like all the characters tbh. I think they're all likable enough that a lot of the like/not like talk for this fic might come more from how invested people are and being nervous about what direction it could go. It's a good sign of how compelling the story is! And even though it has a strong formula, it's hard to tell where it's going to go.
