Lin He returns miraculously after going missing in a plane crash for fifteen years, her appearance still that of a twenty-year-old, but things at home have drastically changed. Her eldest son treats her as a "substitute", her daughter is blinded by a hypocritical cousin and a phoenix man, and her youngest son is plotted against by "friends" due to a lack of love. She neither cries nor makes a fuss, resolving misunderstandings one by one with wisdom and directness. A DNA report makes her eldest son convinced, a bet makes her daughter see the scumbag's true colors, and a confrontation helps her youngest son regain his standing. At the same time, she tears apart the fake best friend who profits off her name, removes the "malignant tumor" that has infiltrated the family for many years, and pieces the family, broken for fifteen years, back to its original state piece by piece with patience and love.
