Princess Mariatine was born with red eyes, a symbol of bad luck, and was isolated from an early age. One day, she receives news that her country lost the war it started, and that her father and brother died in battle. To protect the country from greedy ministers, she decides to marry Chancellor Rozwald, a man 24 years older and famous for being grumpy. The marriage is just a facade, and Mariatine becomes queen under Rozwald's orders, hiding her true intelligence. However, little by little, she feels attracted to the chancellor, who also has a secret that he cannot reveal to anyone.
