A female reader of a romance fantasy novel finds herself transferred into the body of Marienne Didier, the third aide to the Chancellor, Baileon Biers, in the story. Frustrated that the narrative consistently favors the black-haired Northern Duke over the brown-haired Baileon, she resolves to alter the story's outcome. Believing that changing Baileon's appearance and demeanor might help him win the heart of Princess Odette, she pushes him to adopt a colder, more aggressive persona. Despite his doubts, Baileon agrees to the plan, though it causes tension and confusion. As the Northern Duke reappears and Odette shows no interest, Marienne remains determined to rewrite the story in favor of her preferred character.
