Okay so I'm looking for this very old mangas where the author had the fairy tale classics but smut, I don't know how to explain this but there was this dude that had like a library and in the books where the stories of the classics like red riding hood etc and one of the villains ends up out off the story book and realices that his life was a story and the library dude was like a god who oversees the stories in said library,... I don't remeber much of it hope somebody recall this

I'm trying to find this yaoi Manga that I want to save again, it's drawing design is beautiful, is about a redheaded boy who doesn't t have family, he volunteered to be the bride of the mountain dragon who has black hair, he is the last dragon and let's the boy go if he wants to, but the boy decides to stay whith him and tries to be forever with the dragon by eating a scale dragon.

So it's about s guy who wasted his life and the girlfriend leaves him, he jumps from the rooftop and dies, then he mets death who is a woman with silver hair and she gives him the oprtunity to live again with a catch, is what I think I can say without spoilers.
there is a main object that death uses, one of those guns that the bullets spins in the gun.

I believe the lists will come back, and just in case, since I saw that the list we created didn’t disappear, I’ve been backing up my “I’m Reading” list. Every morning, midday, and at night, I check the latest updates, read my manga, webtoons, etc., and add them to the reading list I created.
It doesn’t hurt to have a backup while the lists get fixed, and in case this happens again in the future.
