Lillian Lin grew up in an orphanage. After reaching adulthood, she learns that she is the biological daughter of the Jiang family in South City. Believing she has finally found her home, she returns to the Jiang family to acknowledge her identity, only to discover that her mother has already passed away. Her father, Gregory Jiang, has married his former mistress, shows deep affection for his illegitimate son, and blindly trusts the adopted daughter, Rosa Jiang. In order to gain acceptance, Lillian makes every effort to please the Jiang family. However, her patience and compromises lead only to betrayal. In the end, she dies alone on the streets. Before her death, fate intervenes. Lillian awakens a Negative Emotion System, which allows her to exchange accumulated negative emotions for various rewards, and she is given the chance to live her life over again. Reborn on the day she returns to the Jiang family, Lillian immediately binds Rosa Jiang, the fake heiress, as her task target. This time, she chooses not to endure or ingratiate herself with others. She speaks bluntly, acts decisively, and releases her anger without restraint, using the system to build a new path for herself.
