Currently active as a member of the military band unit, Ryeowook took to the stage to sing his solo title track "The Little Prince" first, before being joined on stage by Luna. The two of them went on to sing a duet performance of Luna's "Night Reminiscin'", originally a duet between Luna and Yang Da Il. Before the performance, Ryeowook and Luna mentioned that because Ryeowook is a soldier, they only practiced separately for the stage without rehearsing together. However, when the performance started, the two artists showed off their professionalism by working together flawlessly. 

Meanwhile, Ryeowook is set to be discharged from his mandatory military service next month on July 10.
