Since the first chapter I felt a kind of anger or disgust for Hideo and Kurami's relationship. I don't know how to explain it, but these feelings grew and also turned into something hard to explain, like something like "two weirdos, but they deserve each other." The relationship between Katsu and Kyouto is another one that follows a somewhat similar line for me but I don't think Katsu should end with her but is ok. In the middle of the story, the discovery that the doctor has a possible strange relationship with Kurami made me really sick, because even though the MC humiliated himself so much for her, I thought that he still wasn't the only one for her. Thank goodness they apparently didn't have the kind of relationship I imagined. And now, in the end, this work made me feel sad, We all already knew what was going to happen, but it was still very sad, sad but beautiful. Many emotions that a manga rarely manages to convey were conveyed, a captivating and different story that left a wound (I'll have to read some cute, one to one, no harem, no tragedy, wholesome romance mangas to heal that wound).
I still don't know what grade I would give this manga yet, I have to digest all this information, but it would be somewhere between 8 and 10.
