Daisy Alpina Rainer is the greatest knight in the Lowes Empire. Her duty is to follow and protect Emperor Franz Juligen Roheas like a shadow. United by loyalty and camaraderie, the emperor and his knight share a strong bond. However, Daisy is in love with the emperor. She had never resented her fate. She was content just staying by his side like a shadow—until the emperor married Arisa Amesis, the empire's greatest beauty, and had a child with her. Consumed by a maddening jealousy, Daisy runs off to the Forest of Illusions to die. However, a magician she encounters in the forest offers to grant her a wish: to erase Daisy's feelings for Franz entirely. The moment Franz feels the terror that Daisy might die, he regrets every moment he pretended not to know her true feelings. Now, Franz sets out to win Daisy's heart back, while Daisy pushes him away. Can this tangled relationship be unraveled? And what is Daisy's true identity?
