In 2012, Catherine dies in a terrorist attack, only to discover in her final moments that she is nothing more than a minor character destined to die early in a novel. After her death, her son, Kyle, becomes a social outcast, lands in prison fighting for the girl he loves, and loses his family fortune to the scheming nanny and her daughter. Refusing to accept this fate, Catherine is reborn in 2026 as an 18-year-old high school student and becomes classmates with her own 17-year-old son. Armed with the trust fund she left behind in her previous life, she makes a powerful comeback. She outsmarts gangsters to get Kyle out of trouble, stays up late helping him study his way to success, and exposes the school belle's fake sweet-girl act in front of everyone. Determined to help her lovesick son see the truth and turn his life around, Catherine takes matters into her own hands. Meanwhile, on a nearby street, Kyle's biological father, who has been missing for 14 years, is mysteriously reborn. A new storm is brewing...
