I feel like this would be a lot sadder if it was shown in the POV of a person who actually did something in life. Maybe an author, and we get to see him write his last book, and we would wish that it would be his magnum opus, I wonder what a depressed Japanese author write knowing he has no time left. Or maybe even sadder would be a young child, who only knows their school, family, friends. We would get to see their parents spending all the time they can with them, I think the last chapter of either of these would make me very sad and possibly cry. But this manga, this just makes me feel empty, it would be pretentious to say that I am the MC, but I do relate with him. Sorry for the blogpost, I just want to write my thoughts down.
