I found this story just now and reading this summary here "rembrary" made me remember what kdrama that i watched before. "Heavenly idol"
Yes it is, I heard the kdrama version was a huge mess ,even adding romance? Even though it's fantasy idol comedy
The cover art is very much different in the story. The story and the art are ugly.its so bad like it would lose your interest. I would appreciate it a little if the art are much better.
