Sandeul dedicated his cover of Lim Jae Bum's "I'm a Candle Before You" to his late aunt, saying, "I want to sing this thinking of the promise I made to my aunt who passed away." He explained that as a young child, he and his aunt would listen to music together. The now B1A4 member promised her that he would become famous and sing on a large stage.

His fellow competitors as well as the audience were definitely taken by his emotional ballad. Sandeul beat out the other singers, receiving 421 points in comparison to Wheesung's 419. Sandeul commented, "I hope my aunt in heaven watched this."
