After the fall of the Kingdom of Jarthewer, Princess Lisselotte and her maid, Hannah, escape to the Grand Duchy of Ralus, home of the princess’s fiancé, Vincent Ralus. Though Hannah has lost her memory after nearly drowning, she stays strong, enduring Lady Charlotte’s daily abuse in hopes of a better future. But everything changes when Vincent asks her to pose as Princess Lisselotte for the 10th-anniversary ceremony of the Jarthewer Republic. Returning means certain death both for her and the princess, but if they can pull off the deception, it may be their only chance at freedom. Stuck between the handsome but cold Vincent and his mischievous and buff guard, Diego, can Hannah succeed in her dangerous role? (Source: WEBTOON)
