In addition to the eye-catching performances, the youngest member of B.I.G, Heedo, who is also making his way was an actor, acted out a proposal and kiss scene with a female audience member, getting applause from the crowd.

Leader JHoon said at the guerrilla concert, "Like our song 'Are You Ready?', we will practice so that we can always be prepared to give our everything in front of our fans. We will be revealing our never-before-seen charms, so please love and support B.I.G as well as our song, 'Are You Ready?'."
