What I love about this story is that neither Dani nor Yeodan are at fault for their relationship not working out.
She's not wrong for spending time with and supporting her long time friends. She's treating him like a boyfriend and not leading on any of the boys, not her fault they have feelings for her, she doesn't even realize they do. I'm not understanding how anyone is getting that shes not treating him well, I can't think of a single thing she's done wrong on this relationship except not changing the way she treats her friends.
At the same time it's not his fault for being jealous and insecure about her friends, especially since we know they do have feelings for her and he's just picking up on it. He's aware that it's toxic to try and tell her to stop being friends with these people and tries to stop himself from having a reaction.
Overall, they're trying their best in the relationship but just aren't meant to be. I'm sad to see it go but honestly it's been pretty clear that they only ended up together because he's the only person Dani is actually able to believe has feelings for her.
I love the way that the two dads parallel each other so well, especially in the most recent chapters. Eustis has a child out of love and is unable to love that child and neglects her. While Leguin has children out of curiosity but clearly cares for and helps them grow in his own way. They are both not the best fathers but I would rather the one that writes a notebook on observations about his children than the one who only starts creating a connection with his child after she minimizes herself to please him.
Also, love how the story is starting to show that Leguin loves his sons too. He clearly dotes on Philomel but I think it's part of how he has different relationships with all his kids based on what he thinks they need. So many stories make fathers not like their sons and it's so weird, I was afraid this story was going in that direction.
