Yu's family became strained after having a child, and her husband started having an affair and rarely came home. Stressed from childcare and her husband's behavior, she developed a mental illness. A self-proclaimed clinical psychologist neighbor prescribed her a mental tranquilizer. Then, changes began to occur in Yu's body. The opportunist neighbor began to seduce her subtly. Eventually, Yu also went to the neighbor's house willingly. Overdosing on the medication, she could no longer turn back and was repeatedly violated. Case number 250625.
