Imagine you were chained to chains of fear. Imagine only breathing the air of curiosity. Imagine living in a white space, where people watch your every move. Imagine that. Live that. That's exactly what Zhang Yixing did for all his life when he was stripped of his mother. For all this time, all he did was stay behind this bars of a prison that claimed his life. Now he is adult. Instead of freeing him, they have Yixing meet people just like him. However, these people know who Yixing was. Now they ask him to help them out. To heal the cold Oh Sehun.
