Looking for this Manga I read a couple months ago and forgot the title and didn't even bookmark it. Hope someone knows it.
It's a pretty intense drama, sick and twisted, and smutty too. I liked the plot a lot so I didn't stop reading it.

The MC is a girl who has a fiance. This fiance knows a popular singer who is also a close friend and went to meet him with her, but the girlfriend was raped by the singer's band mates. The fiance never knew. As the story moves on, the MC is constantly threatened and raped by this singer (pretty much in every chapter. he's pretty twisted but because he had a rough childhood being raped and treated badly in his home) who is ALSO in love with the MC's fiance. Gawd, I'm spoiling this for anyone who is interested.

So there's all this threatening, rape, cheating, and so many damn secrets in this manga, then there's a plot twist where all the characters and past are connected. It's pretty good and annoying at the same time but I still want to continue reading it. It's still ongoing and wonder if it has updated any chapters yet...
