In her previous life, Su Wan, the real heiress, was brought back to the wealthy Su family. But her insecurity and timidity, along with the false heiress Su Ya's careful schemes, led to her being slandered and ostracized. Her fiancé was stolen from her, and she was eventually set up to die in a car accident. Reborn on the first day she returns to the Su family, Su Wan sheds her timid ways and binds herself to a face-slapping System. Sweet and innocent on the outside, a schemer within, she vows to make Su Ya and everyone who hurt him pay. At the same time, she unexpectedly discovers that Gu Jinting, the cold and distant “business devil” from her previous life, seems to have designs on him?
