Dang, being in tripleS means have to learn so many dance variation and details for each song is really hard, they can perform in 4 , 6, 7, 8, 12, 16 , 20 and 24, it means for 1 song they have to learn about 8 formations... excluding Generation, Inner Dance, Cherry Talk, Just Do it, and Door, it's about 9+ song that has more than 2 formations and variations on my personal count
Naky said in the recent video when they were teaching a dance class it's 20 formations they have to learn for the different combinations. They are so talented 👍😊
