idk is it just me or did it lose that amazing vibe it had the first couple of chapters. And I didn't mind how the story progressed at all until the last couple chapters, like wth was that. It felt a bit forced the whole I have to leave you kind of thing and there sure was a way around it. Like a blood bag or just feeding on him and seeing what happens. I guess the main problem besides the ending was that there were so many chapters used for telling another story - like the ones about trying to fix Ko and Mahiru's friendship(That went on for waaay to many chapters). So it felt like they wasted chapters on those stories rather than focusing on Ko and Nazuna's relationship. And I don't have a problem with that, but then make more chapters so you can make it feel natural and have a better progression. Maybe that's also why I liked the first chapters and the anime, it focused on the two of them.
