Aww, that was a really sweet gesture Nanaho did for Chidori at the end! <3
Things are starting to get a little more serious between the two and generally their life. With applying to universities and all that...
But hey, they are finally considering telling their friends about them!! And turns out, they were more "afraid" of getting teased by them, rather than not being accepted, lol... well if that is the reason, I get it. Still, though, it'd be great if they told them before graduation.
Overall, the kids have grown up. They're way more mature than in the last volumes and talk openly about things that bother them, whether it's about their future careers or their relationship or anything. Love it! Great progress (even if it took 100 chapters...)!
