I don't really get the complaints about the ending? The problem is that he gets thrown in front of a train and dies? I felt it was a different thing to have the protagonist die at the end.
I don't get what would be bad about it; it's a very good story to me; I have the feeling it's simply poorly received because it features a lot of sex scenes.

That is why I think it's one of the best harem series ever, because it actually shows the problems therewith rather than the idealized phantasy; and even this is a bit surreal and idealized with how much the m.c. seems to continue to meet suitors, without really having done much to earn it, which is very common in the Harem genre, but at least it portrays the usual problems that arise from all these love triangles.
I also find all these nihilistic characters that just seek to have the world burn to be fascinating, because they're all human in their own different ways despite of it; on top of that, this author does know how to create interesting sex scenes that are all the more arousing due to the tense emotions.
