Really 1960s-1980s horror films were inspired by Film Noir in the 40s. Film Noir was more romance/mystery cause full on horror didn’t exist yet. Eventually this changed in to horror like we know it today. Which shows like “Strange Things” capitalized on.
What you are seeing is two concepts which are inspired by these film movements. Both the black, white, red, and romance aspects. You can also see this inspiration in BTS’ Suga solo “Shadow”, EXO’s “Obsession” or Pentagon’s “Dr Bebe”.
Please investigate before you embarrass your fandom.
I also want to suggest that just in case I’m wrong, everyone should watch the MV many times to check for copying. And buy 12 copies of each album so you have a chance to make sure the 24 Photocards weren’t copied either.... just to be safe.
