Ordinary office worker Anna wakes up one day to find herself reincarnated as Annelie, the villainous noblewoman from an 18+ otome game she once played. However, she has no time to process this new reality before discovering that the game’s storyline has already reached its conclusion. Annelie is already married to Prince Lienhard, a man whose handsome exterior conceals a deeply sadistic nature. Trapped in this unwanted role, Anna is desperate to escape her new husband, but the prince has no intention of letting her go. Instead of granting her freedom, he pressures her to reenact their wedding night, claiming it will help her recover Annelie’s lost memories.

The story unfolds within the confines of a castle where Anna must navigate her precarious situation. As she pretends to suffer from amnesia to explain her changed behavior, she finds herself subjected to Lienhard’s controlling and forceful affections night after night. The central conflict arises from the clash between Anna’s desire to flee and Lienhard’s determination to keep her bound to him, blurring the lines between coercion and the dark fantasy dynamics of the game world she now inhabits.

The main characters are Anna, a modern office worker whose perspective is thrown into chaos by her new life, and Prince Lienhard, whose sweet demeanor gives way to a possessive and cruel nature. Their relationship is the core of the narrative, exploring themes of power, memory, and unwilling attraction. A notable narrative development occurs when Anna discovers a large dog in the castle garden. As the dog grows attached to her, she attempts to keep it a secret from Lienhard, but her plan is complicated when the animal transforms into a handsome man with animal ears who appears outside her window. This event introduces a new element of fantasy and potential escape from the prince’s grasp.
