For Mark, the outside world was a distant dream. The walls of the orphanage blocked him from the outside, all of the children around him, unaware, obvlivious to the world outside the walls. Mark only had himself to converse with about the wonders, the dreams and oppurtunities that lay beyond the walls. However, when a frazzled orphan arrives from the outside world, Mark finds a new meaning; someone that he wishes to protect. But after Jinyoung's arrival in the orphanage, neither of them have the time to settle down and connect before the nightmares of the world seep into the pure orphanage, once free from corruption. The drug. Once both of their lives fall in danger, to what extent will Mark and Jinyoung fight to protect each other and flee from the grasps of the older generation?
