Shen Jinnian, born with a lucky koi physique, is reborn back to the first day Shen Qianxue—the real daughter—is taken into the Shen family. In her past life, to repay kindness, she bound the Shen family’s fortune with her ancestral jade bracelet, exhausting her own luck to protect her adoptive family, only to be misunderstood as a disaster star and die tragically. After rebirth, she resolves to only help 5 times to resolve the Shen family’s crises to settle karma, then cut all ties completely. She repeatedly warns the Shen family of impending disasters: elevator fall, stair accident, car crash, and secretly defuses them. But the Shen family believes the fake daughter Shen Qianxue is the lucky star, and accuses her of being a jinx. They take her room, her birthday, and even force her to remove the bracelet at a banquet. The moment the bracelet shatters, the Shen family’s fortune collapses, and disasters strike one after another. Meanwhile, Shen Jinnian is recognized and taken in by her biological Qin family. Her true koi power protects the Qin family from all harm, revealing the Shen family’s ignorance and ingratitude.
