dancer herself. She's on youtube day and night watching this stuff and knows I like anything UCLA so we bond and have fun watching together at times. She told me there are at least 3 K-POP dance groups at UCLA (Koreos, Seoula and ModernX) and they are very famous in the community for doing dance covers on youtube. Can't believe how many views these have. Your wife might know some of them.
Koreos covers 7 BTS songs in 7 minutes (3 Million Views!)
My niece's friend is a dancer in this video of a dance cover of a group called Twice which she says is the girl group equivalent of BTS.
Best of all, these are all Bruins so Go Bruins!
