Five years ago, Shen Wantang was sent to a mental hospital by her stepsister and her fiancé. She gave birth to twins, a boy and a girl, alone in the delivery room of the hospital that day. Five years later, she returned to the city with her two children, and everyone thought she was crazy. Her stepsister laughed at her at the wedding: Did she come back to seek death? Gu Zhan cornered her: Who are you? Her five-year-old son grabbed her clothes and whispered softly: Mom, don't be afraid, I will protect you. Shen Wantang smiled slowly, and that smile made everyone present feel numb. She whispered something, and the whole wedding scene exploded.
