They would make the cutest throuple, I'm so happy for them.
Also, also! Sayo did it! She got the girl!!! I'm so happy for her. She's such a sweetheart, and given the arrows we've seen from her, she's been managing her strong desires very maturely.
I'm also so glad we get to see a childhood friend win. I'm not as much of a fan of it in a heterosexual context, and I can see why the destined childhood friend -> partner thing is subverted so often (thanks to an article I read a while back about the trope that I can dig up if anyone's interested) but when it's between women, and it's played straight (no pun intended lol) it hits different. One might think it's the fact that gay crushes on your childhood best friend are actually extremely rarely fulfilled for a variety of reasons despite how common that situation is, which could bring readers a sense of catharsis, but I don't even think that's what makes this so satisfying and compelling. I can't quite put my finger on it right now, but something tells me it's about how the story interacts with genre. Like, because the "childhood friend loses" thing is so solidified, seeing Sayo rise to overcome it not just because she's the one selected by chance to win a harem thing, but because she personally undergoes a great deal of development to unlock her inhibitions about being honest with her feelings, while the MC simultaneously grows to become someone who can accept those feelings, and they both find that being together in that new way really works for them--it's sort of like they're defying fate, and because it's written with verisimilitude we as readers can receive it as this very hopeful message, that, yeah, you can put in the work to maybe make things work out with that girl you like.
Lmao, I guess I did put my finger on it. But yeah, it's like, maybe because I spend so much time on the internet I see that "useless lesbian" thing over and over, to the point where sometimes it feels like most of the gay women are going "haha, this is just how it is"--there's this wider feeling that we can't get things to work out, that we can't get the girl, and so it's really cathartic to see Sayo break through that same kind of anti-predestination. Does anybody feel that, is that for real?
It also helps that she's adorable totally deserves to get what she wants and be happy. She's so kind. What a sweetheart.
