YES! DELINQUENT YURI NEVER DISAPPOINTS!
(I've read, like, two more delinquent yuri series but whatever)
Anyway, really enjoying this so far. While reading the first volume it kinda felt like one of those series that continue endlessly without ever having any actual progress...? But I was very pleasantly surprised with the more recent chapters.
I really liked the failed confession we got from the side couple.
LET ME EXPLAIN, I SWEAR IN NOT SOME SADIST THAT WANTS KISHI TO SUFFER
I did root for Kishi; the thing is, from the start, or at least very soon, I got the impression that her feelings weren't reciprocated. I don't think that Himekawa likes Hana, but it was pretty obvious that she saw Kishi as a friend. I'd actually be a bit disappointed if the author had her accept the confession, cause it'd feel like they hadn't given any proper thought when writing her character in the previous chapters.
Also, the fact that the main characters are actually in a very similar situation makes it very interesting to see how things will turn out for them. You freaking out at the realisation of how fragile their relationship could be seems to me as a clear sign that she does wish for them to be something other than friends (since that was what disrupted the balance of their friends' relationship); though I wouldn't mind the friendship route honestly.
I've come to really like You as a protagonist. She's kind of closed-off and meddling and insecure, but somehow that makes it very liberating when she takes the first step to share her feelings.
