Thank you for posting!
I always love watching dance cover videos like this from current girl groups to original girl groups.
It just warms my heart, knowing they [ and the labels ] appreciate the original artists' music.
I might have to be a fan these girls now because they are only 4 members, which makes it so easy for me to know and memorize their names and faces.
I realized they're pretty much wearing the similar outfits from GG's early eras ~
the girls on the far right and left seem like Gee, scratch that-- the one in the far right was I Got A Boy--, the girl with the skirt was Girls' Generation, and the girl in the uniform was Genie.
Also, thanks for introducing a new girl group to be a fan of!
And I read some profile video of them, and 3 of them were former members of other groups.
Regardless, I'll be a fan of the whole group.
I'll update you on my bias later.
