Forgot name of bl manga

I’m looking for the title of a manga (I don’t remember exact details so some info may be incorrect) about a demon who comes to earth with a fallen angel who poses as his brother and they work at a coffee shop owned by the demon. The demon uses the shop to screw other dudes. Falls for an office worker - his boss (I think it was his boss or just another college) hunts and kills demons on earth. College/boss (c/b) dude tries to kill demon. Human helps save him. C/b comes back to try again. To prove that the demon won’t hurt his human lover, he rips off his horns and becomes human. I was gonna recommend to a friend but forgot the title
