(First I watched this drama because of bl. And if you re watching it for the same reason drop it because there is no bl whatsoever.)
However I will try to be non biased but no promises....
Let's begin with the review

STORY: The story seems a quite immature to me. I have forced myself to watch 4 episode because watching another episode would be a great torture. The story played well for first episode but in the next three episode(for me) it doesn't feel good. It was off pace and everyone started dying(of course it is horror and death is evident) but whenever someone died no one would grieve for them. Hell your friend died and you are just enjoying your life? (This was a big shock!)

Acting: (Well I don't know much about acting so I will judge them with my current knowledge) Kin, Nat, Dan, Aya, Dan and Brave acting was done very well however Praewa's role wasn't handled very well. Lilin's acting was good (I don't know much about her)

Music: It was okay. (I don't have much to say regarding it because I was too angry at the story)

Overall/Rewatch value: I can't finish the rest of series so I am pretty much sure I won't rewatch it. (I will if I want to anger myself to death that is. And that is not likely to happen)
