How scary is it? Can you watch it without getting nightmares?
Don't watch it at night if you don't like being scared. Sometimes ghosts appear suddenly that scared the hell out of me a few times. I agree with the other commenter "It's more of a supernatural drama than horror."
The man had helped her kill 3 people, just to stay "young and beautiful" for him. He was a murderer, not an innocent.
Did I write he was innocent? I was emotional when I wrote my comment, I could have been more specific. I understand where you are coming from, but it feels wrong to me. Maybe I watched too many crime series and got used to them catching the criminals alive. Or maybe because the male lead is supposed to be an upstanding police officer. Anyway, I won't watch it.
Disney talking cup was the first clue this is not for me. When the female lead let the demon kill the man because "A gentleman should always keep his word." I lost it! Yes, he lied to a woman (as a woman I hate him for it) still letting him be killed by the monster?! What moral this drama teaches?! If someone would reason 'but she will change', the male lead let him die too! + He is a police officer!
