This arc was really rough for me, I really hope we get to see Rina's situation improve more and more in future chapters. The part where Kina thinks that for children their parents are the most important people really hits the mark, even with all their imperfections, they are the first people kids learn to look up to.
If I ever have children I hope I do good by them.
I'm happy we got to see Shun acting as a big brother, they even got into a fist fight, that's so endearing!
I also liked the "old Fumi" gag, and that flashback where he's holding hands with smiling Sakurako made me feel so warm. I don't think they'll end up a couple so don't lose your wigs y'all. Growing up Fumi will just learn about the different kinds of love besides romantic. Anyway another thing I'm really into is how present was the father, we've already been told that he adores Fumi but seeing him being so "way too into it", bringing a professional camera to his son's sport event, is really heartwarming. And also his final remark when he wishes the mom was there to see really ties up this beautiful chapter!
This... Was something special
