There are good days and there are bad days. SISTAR's Hyorin may have performed under expectations in the first challenge of 'Unpretty Rapstar 2', but that looks to be a one-time thing. Her performance in the latest episode had judges impressed!

Hyorin and Kasper battled against each other. And at first Kasper seemed confident knowing that Hyorin didn't so well before, but once she actually started her rap, she seemed a bit tense and worried. She was judged to be "too much" and a perhaps a bit over the top by the judges. Hyorin on the other hand, surprised with her great performance.
Block B's Zico complimented Hyorin, stating, "It seems like she brought a rap that we could become immersed in, and did really well."
To find out the number of votes Hyorin and Kasper received, you'll have to watch the third episode!
