Episode 4 - S1.E4

Lee Bumsoo joins the show. He sits unseen in the bus as the Girls' Generation members are driven to the filming location and talk about him. The girls go to a supermarket where they choose gifts to buy for Lee Bumsoo, splitting into a short group and tall group. The haunted school setting from the previous episodes is replaced with an outdoor setting at a park and a bright indoor set. Several members then have one on one acting lessons with the actor.
