After learning her true identity at age 25, Su Qingwan falls off a cliff and is reborn back to her 19th birthday engagement banquet. Publicly tearing up the engagement agreement sold by the Su family, she forms an alliance with Lu Shiyan, who appears frail but is actually the power holder of Yaochuan Group. Together, they fight against the exploitation by the Su family and the power seizure by the collateral branches of the Lu family. Using the top-tier technology codenamed "Bluebird," Su Qingwan founds Wanxing Capital to investigate her background, uncovering the secret of how the eldest branch's legitimate daughter of the Shen family was swapped nineteen years ago, orchestrated behind the scenes by Shen Zhaokun and Zhou Meilan of the Shen family's second branch. She gathers evidence, using public opinion and the law to bring down the villains, and ultimately reunites with the Shen family, reclaims her identity, and finds happiness.
