Around five years ago I read this yaoi and finished it in one night. It was about this guy who struggled with depression and had a crush on this guy he called “Habit-hyung” or something similar to that. The main character had a crush on the guy, because he helped him work through his depression. He worked from home and his crush introduced him to a man who was eight years older than him. The man became his roommate. They began having a sexual relationship and fell in love. It was later revealed that the new roommate had a lover who died of cancer a few years prior. I have looked everywhere. Does anyone know it?
