At a school located on the outskirts of the city, the members of Twice (with the exception of Jeongyeon ) arrived at the invitation of an unknown classmate. In the place, during the day, they held a sports day divided into two teams, including games such as jumping rope , penalty kicks, Korean bubble suit wrestling and limbo , among others. At night, they had to return to the darkened classroom, finding hidden codes, with ghosts hiding along the way.
