A noblewoman is deceived by her cruel sibling and forced into a life at a brothel. Using her circumstances to her advantage, she rises to prominence within the establishment before her life is cut short. She awakens again at the age of fourteen, armed with the knowledge and experience she gained in her previous life. No longer the naive young woman she once was, she now seeks to reclaim what was taken from her and ensure her own survival by any means necessary.
