He Wenjing, who married far away to a small seaside town, is severely allergic to seafood. She repeatedly warned her mother-in-law, but Li Xiuying, who lacks common sense, sneered at it—disliking her for being delicate, fussy, and ignorant of old rules. On the first day of postpartum confinement, the mother-in-law fed He Wenjing a nourishing seafood soup without authorization, causing both He Wenjing and her full-month son to suffer severe allergies and end up in the ICU. Yet the mother-in-law remained stubborn, and with police reports yielding nothing, He Wenjing no longer tolerated it. She wants to use her own way to make this elderly woman, who has low cognitive awareness, a strong personality, and refuses to admit her mistakes, see with her own eyes how she tore a family apart.
