Terminally ill girl Jiang Zhiya has only one month left to live. On the verge of death, she binds with a role-playing system, entering H country's top academy under the identity of "Bai Yunxi". As long as she successfully hides her true background for a full year, she can obtain a healthy body; once anyone produces evidence to expose her, death awaits her. She navigates among influential figures like Quan Zhengyu and Yuan Junxu, relying on acting skills, resources, and a clear mind to break through step by step. On one side is a dangerous game under a false identity, and on the other is the older brother she worries about in her pain. To survive, she must turn every step of disguise into a path to life.
