The story takes place in a mental illness sanatorium-Hideki Hideki (Xiaofuting) was sentenced to death for killing his mother and wife, but miraculously escaped death during the execution. Ah Zhong (Ayano) was once an ordinary office worker, but was discriminated against because of his increasingly serious auditory hallucinations. Finally, he lost his working life. Yuji (Komatsu Cai Nai), as a female high school student, strongly resisted going to school, locked himself in his room all day and squatted at home, and was finally sent to a nursing home by his unbearable parents. All kinds of patients live here, each with a tragic past, but they form a special connection that is similar to but better than family members, but the occurrence of a murder upset this hard-earned balance.
