Synopsis: Kinben na Akujo wa Imayo de Yarikaesu

The daughter of a duke, Belinda, has lived a clumsy, diligent life as the fiance of the crown prince, Raymond. However, he dislikes the earnest Belinda and has to rely on her half-sister, Margaret, for help. "I must be grateful to Margaret. If I work hard, Raymond will surely love me someday...!" Belinda believed this, but one day she was arrested on suspicion of "murdering the queen," a crime she had no memory of. As she was dragged to the execution platform, she learned in her final moments that Raymond and Margaret were in a romantic relationship, and that it was Margaret who killed the queen. She had been framed by the two of them all this time... Belinda, burned by the flames with strong regret, woke up again to find that she had returned to death two years before her execution. "I won't make any more mistakes in this life. I will walk the right path so they won't use me again." With this determination in her heart, she approaches "a certain person" who was the cause of her execution in her previous life...!? Belinda was slandered as a "wicked woman" in her previous life, but using her superhuman diligence and the knowledge from her previous life as weapons, she rises to the top of aristocratic society!! The Duke's daughter's satisfying revenge begins now.
