It is a mystery.

Okay, I had no idea a Gone With The Wind musical even existed, but I am sincerely impressed by the cheese factor of this South Korean version. K-pop idol Seohyun plays Scarlett O'Hara, and while she makes a lovely stand-in for Vivien Leigh, I really don't understand the goings-on in this scene. Why the pop music? Why the acrobatics? Why the girls in their bloomers? WHAT IS EVEN HAPPENING HERE?
