Chaeyeon in particular is grabbing a lot of attention as she has not appeared on Korean TV for three years!  Visiting the house, she was surprised at seeing the camera in every spot, saying, "I took too long a break from broadcasts.  It's the generation of technology."

A special teaser just for her was released, as well, on October 16.  Check out the previews (which include a lot of fun dancing and acting) as well as the broadcast on October 19!
