Hi, I'm looking for a BL manga, help please.

I remember guy A had the power to see the emotions of people like colors and forms floating around. And guy B had always a kind of dark smoke floating around him, which, intrigued and scared guy A. Guy A was like a host/rental boyfriend and somhow he helps guy B with some thungs and then they get along. Guy B was a rico guy with an emotional blockage and studied psichology/psychiatry to understand own and others emotions. And B guy pay to rent guy A and have time together.
