Since debuting, UJU always wanted to promote on a show at least. This show was a dance show which she strongly was well known for. Her choreographer Maya and her male dancer Min-jun wanted her to promote on Hit the Stage as a guest performer. She wasn't really apart of the show but will showcase her dance skills to everyone. UJU and her certain dance members pick by Min-jun and Maya, walk to the stage. Since she was a guest, Maya wanted her to be a mystery which is how Mystery Lady came to be. Her outfit red in the mist of black and white suits. Her outfit, showy but was modest with her suit jacket but in the middle of the dance it would be removed. Her favorite dancers Hiroto and Chae-min who were in the mist of the dancers kept her focus. They would make it seem like she was disappearing and reappearing when it was time.

Everyone got in their places after the MC announce her as a mystery Lady. Could they guest who she was. Of course, They should know because she was the only, brown-skinned idol there was. Once the music came on, it was time to begin.

Everyone oohs and ahh looking shock at the complexity of the dance. The moves sharp and sensual in a sense. The guys wished to be the male dancers as they got to be in such a dance. Once the dance of over, with the final pose, clapping with intensity. UJU and her Team bowed in respect to her peers as the MC came to her.

"Yes, our Mystery Lady, any guesses". Mc says with a eager smile.

They started shouting out guests from Beyonce to Rhianna or Melanie Fiona but only one person got it right and it was Ten.

"UJU from MAMAMOO!"

"Oh My God, It's UJU from Mamamoo"

UJU introduced herself bowing as the MC thanked her for being there. She was going to be there for two Concepts. Uniform and This Love. She is an amazing dancer people in the crowd said. She ended her comments with please take care of me with a small smile.
