I am looking for the name of a yaoi manga. The manga is about a guy from the human world who works for a company that has something to do with hell. And the guy has to serve or work for one of the demon king rulers and they have sex and fall in love. I do remember in the end of the manga that the demon king was reincarnated and turned human and the guy that was in a relationship with the demon king ends up meeting the reincarnated demon king and starts a relationship with him. Well that's really all i can remember about the manga so if you can help me figure out the name of it then thankx a lot. 😉
