The doctor recommends transferring her to the isolation ward, which deeply saddens her mother, who doesn't know what to do. Zheng Duo En confiscates Li Bing Xi's favorite computer, leading to a confrontation where Li Bing Xi mocks her for once having a mental illness that caused a patient's death. Zheng Duo En doesn't say much, but she realizes that many mental patients have suicidal tendencies. The head nurse says it's their way of seeking attention in a different way.
