Poor Douma, the Title Won't Get Approved

No CP. My take on Douma loves nobody. He has a slight transmigration twist, but he is a thoroughly awful person.

This is a no-one-can-be-saved story. Those who are destined to die will still die, and even those who shouldn't die will end up dead somehow (?)

I have no outline. I want to make Douma even more detestable than he is in the original, so please, don't hold back when you beat him up. You can also call him Dark Douma. Since he becomes even more hateable, Dark Douma will die in the end. This chuunibyou brat will get what's coming to him, and I hope everyone shines the light of righteousness on the comments when we reach the ending.

One more thing: the author's mental health is perfectly fine. Please don't conflate Douma's behavior with the author's.

Theme: What's contradictory about liking Douma and wanting him to die?
