On September 30, TVXQ held 'TVXQ! Special Comeback Live - YouR PresenT - ' at the Jamsil Indoor Stadium.

During a segment in the concert, Yunho received a request to cover a girl group's dance. As he looked a little nervous and flustered, Red Velvet's "Rookie" started to play in the background. The momentary shyness disappeared as Yunho danced to the sound of the music which caused the thousands of fans in attendance to scream in excitement.
