This is an idea based on a few Japanese MVs I know who are based on topics or plots that you most likly would never see in a Korean MV
Openly gay kissing and promoting being homosexual
A song about hitting your toe
Overweight background dancers
A band with a gender neutral vocalist
Vampire and death/suicide
A song about cheating on your girlfriend
Being an excessive possessive girlfriend
Handcuffing and blindfooling someone in a sexual way
Prostitution (Or how to tell men to fuck off) + twerking
Openly using the word "Fuck" and excessivly talking about sex
A love-triangle between men
Heaving a mental dissorder
Questioning the human race
A song about being bi-racial
