She is the princess he is marrying, but she is the substitute for the white moonlight in his heart. Ten years of infatuated love, three years of humiliation, in exchange for a bowl of heartless potion that he personally fed and a slap in the face. Her heart turned to ashes, and she died with a smile on her face. Later, when he discovered the wooden box she left behind, he realized that he had personally driven to death the woman who loved him most in the world and was also his true savior. From then on, the prince who had the most power in the world lost his love forever and could only burn his heart with fire in endless regret and become a madman for the rest of his life.
