Name

Songwriting and musical style

Before I even make the music, I draw out the performance in my head. After I think about the overall mood, outfits, props, dancers' movements, and the character of whoever is singing the song, I write the song and participate in the choreography and costumes before eventually going on stage. When creating a performance, what is just as important as the music is the fashion.
In an episode of TMI News, Hui revealed that he arranges songs in his sleep. "I seem to get more stressed than I realize, because I've been arranging songs in my dreams. My members keep waking up to the sound of me singing. I've been singing in my sleep."
