hello

can someone tell me the name of this bl, please?

It's about a demon who goes to earth/human world and opens a coffee shop with his follower. He uses his magic to sleep with men to become stronger and grown his horns. He meets a human who he tries to charm into having sex with him but fails....

I don't remember any name but the uke was blonde and always wore his uniform out, he had a collar on with thick leather bracelets. The same has black hair and is tall.

Thank you in advance!
