The members go to the swimming pool together for the first time. A special coach is invited to help with their training, and the members are tested to see their current level. Even though it was a short training, they improved a lot. After training by themselves for weeks, the members are gathered at the Jamsil Tower. They will do a vertical marathon which is going up 123 floors by stairs.
