In her past life, Yang Miao was bitten by Beibei, a Chihuahua whom her mother regarded as the vessel for her first love's soul, and was finally brutally murdered. Reborn overnight, she returned to the day she was first bitten by the dog. Her mother favored Beibei, treating him as a son, and even sparing no effort to harm her biological daughter. Yang Miao no longer passively endured, pretending to compromise, secretly collecting evidence of the conspiracy between her mother and her first love Zhao Sen, figuring out the superstitious scam, stepping by step awakening her father, and joining forces to set a trap. As the truth unraveled layer by layer, Zhao Sen's plot to harm was exposed, everyone fell into the net of the law, and Yang Miao finally broke free from the tragedy, starting a brand new life with her father.
