Aideen, a respected daughter of a duke, was the Emperor's trusted assassin and leader of 'Owl.' Despite her loyalty and sacrifices, she faced betrayal and a death sentence by guillotine. As her Lord abandoned her, she lost her life, only to wake up as a 17-year-old. With a desire for revenge, she resolved to obliterate Ferdi, a nation the Emperor held dear.
Unexpectedly, the Prince of Diceon, who ordered her execution, began to interfere in her life. He admired her beauty, particularly her red eyes. Thus begins the story of Aideen's second chance at life to avenge those who discarded her and destroy her motherland.
