Wow, that's harsh.
SISTAR were were reduced to tears by a cold audience at a school concert recently.
Hyorin, Soyu, Bora and Dasom filmed the special for Mnet's School of Rock "energy attack" special.
The episode saw the girl surprise middle and high school students with a mini concert as a reward for their stressful studies.
However, despite the sweet gesture, their performance was met with crickets. Total silence.
So taken aback to the total lack of applause, the "Alone" singers, who are one of the hardest working groups in the industry, welled up.
But was the incident for real? A rep for the show tells IdolWow! things aren't always what they seem.
"The students end up surprising SISTAR with a performance of their own," a rep says.
