At the exact celebration event, they said Pink's story or couple were added to the story.
The original story did have a vampire (check out opening credit in the original part i postes on pg 3). The head ghost or boss was a pee dip aka vampire. The nangek's job as a ghost was to get blood from guys for him.
This is the 3rd remake. I watch the original but not with kade and noon. But this I watch to see the difference. Of course already this is a vampire. A lot of romance than the first. Interesting. Im scared to watch ghost movie alone. It has to be daytime and peep around
