H.U.B very recently made a comeback with a new single, "The Day The Cherry Blossoms Bloom". Next up for H.U.B's promotions will be a solo debut of member Rui - known as a gold medalist at the '2018 Idol Star Athletics Championship', a former 'Mix Nine' contestant, and more. 

Rui's solo single will showcase her charming, healthy musical color. The song is set for release some time in May.
