This book tells the story of Lu Cha, a homeless woman who, in order to survive, takes the place of a patient who looks exactly like her and enters the Sixth Hospital, a facility for mental patients. At the Sixth Hospital, Lu Cha unexpectedly becomes estranged from her neighbor Yu Cha, a fellow patient. Under Yu Cha's attentive care, Lu Cha not only gradually adapts to life in the hospital and thrives, but also gains a lifelong friend, He Tao. However, beneath the calm surface, undercurrents surge, and Lu Cha gradually discovers that the Sixth Hospital is fraught with danger, seemingly hiding a huge secret. To escape this crisis, Lu Cha resolves to lead the other patients in a breakout from this "cage." Just when she overcomes numerous obstacles and believes she has finally won her freedom and achieved victory, a shocking truth emerges—she was originally a patient at the Sixth Hospital.
