Synopsis
At a female student exclusive-cram school, three girls, You-jin, Boram and Da-young share one room. Living in the suffocating atmosphere of the cram school is already more than they could take, but it is another story to get along with other strangers in the same room. The stress attacks You-jin most: She begins to see what happened at the previous prep school, a fire breakout. The fear from her own vision is keeping You-jina back and the competition over the score starts to take a toll on the friendship she has built with four other friends.
