On February 22nd, MBC's "Starry Night Radio" will host two very special guests, as Insooni and TVXQ will make an appearance together to engage in a special joint performance. Insooni, who began promotions for her new song "Uppercut", will be performing it live through "Starry Night Radio", and TVXQ will perform alongside her; it'll be a special occasion for the duo as well, as they professed that Insooni is a senior they've always admired. Known for enjoying collaborations with other artists, like in Jo PD's "My Friend" and Mighty Mouth's "Smile", fans are looking forward to hearing her newest effort with Korea's top idol duo. The staff of 'Starry Night Radio' promised, "They will deliver a special time in which there will be no generation gap, as they will take turns singing a verse. Please look forward to it."
