At her engagement party, Ando Yoruko was pushed into a pool by her stepsister Yuruko while her fiancé, Sakurai Hideichi, ignored her drowning to save Yuko instead. Rescued by Rando Kurazo, a furious Yoruko dumped Hideichi and impulsively married Kurazo. But her father, greedy for her late mother’s company, refused to recognize the marriage and humiliated her. Vowing revenge, Yoruko exposed her ex-fiancé’s schemes and took back her inheritance—with Kurazo, secretly the company’s CEO, backing her every move.
