Our female lead Norah had a horrible life, she was abused and abandoned at a young age. She was never loved by those who was to be her family (except for her grandparents). She was engaged to the crown prince Ryan, but was let down by him multiple times. When sent to war she thought she would have him upon return, but he was already married to her younger sister. To make matters worse she was sent to prison for treason. The day of her execution her younger sister Ramona visited her.

To hear all this, the little will that was left of her was gone and she was filled with rage and sadness. When brought to the guillotine she shouted her curses to the whole empire and imperial family. The blade fell and she took her last breath but that doesn't mean her story end there. By a miracle she regressed to her 17-year-old self. Now she plans to get revenge on the empire and destroy it beyond measures. And nothing will stop her.
