It's funny to me how some will complain about a supposed "lack of development" in their relationship and use how long this manga has been going on to advocate for something more substantial between Mori and Senpai, but storywise it hasn't been as long for the two of them. Sure, this manga reads like the longest slice-of-life in existence and there are many fillers, but since it's about slowly building their relationship, I believe even those "filler" moments contribute to said development. Besides, take a look at how MANY yaoi mangas out there usually start: with the seme r****g the uke and then the uke immediately falling in love and forgiving him, and then they live happily ever after. Sounds familiar? That's exactly how Koisuru began, but senpai refused to follow the trope. Even if he does end up developing feelings for Morinaga eventually, it makes much more sense to build around that event and to explore their psychology to the deepest levels than to just rush things for the sake of saying "see, they've taken the next step in their relationship". Because, again, storywise, it hasn't even been that long for them. They're still learning how to "be" together. And personally I think it's amazing how even after all this time and all that Mori and senpai have been through this story still sparks interest, because it deals with love as something that you build little by little; it's the small things.
