Hye-jin and Whee-in were, what 21 almost 22? Yong-sun and Byul-yi were just a few years older? I'm in awe at the amount of command of the stage they had. Raw talent only gets you so far. They had to have worked so hard to get that polished at such a young age. They have peers(no names) that still in 2023 can't perform in front of a crowd at that level. And I have criticized RBW plenty for failure. But wow Kim Do-hoon and his team sure did give these ladies all the tools they needed to succeed. I know Immortal Songs Melody gets all the attention, and rightfully so, but this performance of Decal in the same concert is soooo amazing. I get chills every time I watch it.
