24-year-old Kim Ha-rim dies in a car crash, only to realize she's the tragic, doomed first love in the novel she wrote. Worse, she witnesses the horrific futures of the two children she left behind. Miraculously reborn as her 18-year-old self—with her 18-year-old, deeply scarred son and daughter now her peers—Ha-rim is given a second chance. Armed with knowledge of the future, she races to reclaim stolen assets, reform her rebellious son, heal her traumatized daughter, and dismantle the villains who ruined their lives—all with the unexpected aid of Yoo Jun-hyeok, the male lead she never got to love. This time, she's not just writing their story; she's rewriting their destiny into one of healing, success, and family.
