Yeah, it's originally from the 60s I believe.
I'm so worried about Boram! She looks about 3 pounds away from death...
I do think Areum is a suitable replacement for Hwayoung. For starters, she's much better than Hwayoung was in 2010 when she first joined the group. Plus she can sing! Give her two years like Hwayoung had and she'll be even better.
