He read, "In 5th grade, we drove 4 hours so that I could learn music. That little kid has grown up and is now living his dream by being a member of B.A.P with the name Zelo. I will continue to be my best for you. I will strive to be the best son for you."

An official also revealed that as Zelo left the stage, many fans in the audience were crying as well.

On the other hand, B.A.P made their comeback stage on February 15 through KBS "Music Bank" with their new song, "ONE SHOT."
