Introduction: Ying Jiani, a freshman girl, went to study in the evening on her first day and saw a strange-looking boy in the women's bathroom. The boy said something, turned around and jumped out of the window. Ying Jiani was so frightened that she fainted to the ground. After waking up in the hospital, she told the teachers and classmates around her about her experience. Everyone looked at each other, there was no such thing as a student jumping off the building, Ying Jiani must have been hallucinating. Suspected of having mental problems, Ying Jiani fell into depression and had nightmares. One day not long after, she received a strange text message with a name "Hou Yixiang" written on it. Searching for this name on the Internet, Ying Jiani discovered that he was actually the boy she saw. However, this man committed suicide by jumping off a building a year ago. Could it be that she saw a ghost? In order to solve this doubt, Ying Jiani approached Dr. Gu Yiheng from the University City Institute of Psychology for help. At the same time, unknown dangers were approaching her step by step.
