Show me the power of SNS~." Yoo Se Yoon tweeted back, "Psy is popular so he gives a free concert, we failed so ours is free," and and made netizens laugh.  

Yoo Se Yoon previously said, "the tickets weren't selling, our concert failed. I'm sorry, but we will still be performing on Saturday and Sunday at 6 PM, at the Children's Grand Park!! It's free, come to see it, I'm sorry, tears."

Comedian Park Sung Kwang also said around the same time, "I came for the Sungkyunkwan festivities. But..but..everyone went to watch Psy's concert, so no one is at the school. I'm jealous of Psy~"
