I saw the video of Park Si-young, who debuted with Koi Kids, practicing the choreography for "New World."

It's the unwritten rule that when a Produce 101 group debuts, they also show a signal song choreography video filmed by the debut group members, right?

Anyway, Koi Kids is trending too.

Shinsekai seems like a true masterpiece.

It sounds good no matter when I listen to it.

Siyoung's dance is also stable.
