Does anyone remember this one manhwa?

I didn't read much of it. From what I remember, the MC (uke) had lost his lover and was really depressed the first episode. He was lying in bed with the sunlight peeking through and there were these like phantom images of his late boyfriend in his room. He was like completely emotionless and was struggling to move on. The reason I dropped it was because it just felt so unbelievably sad, but I'm curious to read it again. This is all I know; I don't remember anything else about the plot. I assume it was about him learning to let go and start loving again or whatever.
