I think the cycle is repeating again because firstly it's a movie that the High School AU of the gang is watching and secondly I think vivinos wanted to explore more about the dynamics of the couples in different settings? Not sure though.
I think as in general female singers and idol's bodies are sexualized by the industry for profit, the same happened for Mizi when she was sexualized for the posters and promotions.

Just released new video!!!
Thoughts on it?
I feel like them replacing the aliens with humans and the message behind kpop, made it really dark
