Red Velvet opened up about the struggles with learning the new dances.
On the August 22 airing of MBC's 'Weekly Idol', Red Velvet performed the highlight moves to their new songs. After watching their performance, MC Lee Sang Min commented, "I can feel your power."
In response, Red Velvet revealed, "We learned the 10 songs in just a month, not even a month," and added, "It was very confusing."
However, Joy shared that she had fun with the dances and said, "But what you get in return is as great as the hardship you endure."
