On October 1, EXO-CBX consisting of members Chen, Baekhyun, and Xiumin, performed at 'Fandom School 2017 Korea Music Festival' which was held at the Gocheok Sky Dome.

The trio performed tracks "The One" and "Hey Mama" as the audience was blown away by their powerful choreography.

During the last part of "The One", Baekhyun took the time to send out a romantic heart pose to his dear fans when a sudden firework explosion startled the idol.
