On November 20th, SBS's '1000 Song Challenge' aired a new episode with SNSD's Jessica as one of its guests. Prior to her performance, Jessica explained, "I was a trainee for seven years, starting from 2000 to my debut in 2007." She continued, "I don't usually cry while listening to music, but this song made me cry a lot." Intrigued, the hosts couldn't imagine what kind of song would make the 'ice princess' cry, and Jessica revealed that it was none other than Gummy's "If You Come Back To Me". Check out her performance below!
