Hi y’all!
I’m looking for a rlly popular manhwa that I used to read about this dark haired girl and white haired guy.

It’s pretty psychological from memory, and during the start the guy is in a coma and visits the girl in her dreams?

The girl has a “friend” who is obsessed with ruining her life and basically steals everything she holds dear.

Also the white-haired boy/ML used to be an idol but was involved in some sort of rumor/scandal which was untrue but ruined his career?? and then he ended up in a coma..

TIA :)
