The Imperial Palace of the Roen Empire. The banquet hall, where hundreds of chandeliers glowed with golden light, was filled with the laughter of nobles and the sound of music. Today was the day of the ball hosted personally by the Crown Prince of the Roen Empire, Elian Roen. Countless young ladies looked at him with fluttering hearts. Dazzling pink hair like the sun. Beautiful green eyes like emeralds. And a perfect appearance that everyone acknowledged. However, Elian's gaze was fixed on only one person. A girl entering the banquet hall entrance. A beautiful Crown Princess with bright green hair and pink eyes. The heir to the Claudia Empire, Penelope Claudia. As she appeared, the atmosphere of the banquet hall shifted. It was as if sunshine itself had walked in. The nobles marveled, and Elian smiled without even realizing it. "You're here." The person he had watched for a long time. The person he had called a friend. And his first and last love. However, Penelope smiled brightly, unaware of his feelings. No. Perhaps she knew and was simply waiting for him. The ball began and time passed. Penelope was busy greeting numerous nobles, and Elian could hardly find a chance to speak with her alone. After a few hours had passed. Feeling a bit stifled, Penelope quietly headed to the garden. The quiet palace garden bathed in moonlight. A cool night breeze carried the scent of flowers. Penelope leaned against the railing and looked up at the sky. Just then. A familiar voice was heard from behind. "Found you." Turning around in surprise, she saw a familiar face. It was Elian. He slowly approached her. Not as a friend, but as a man. And today, he intended to tell her. The sincerity he had hidden in his heart for years. Under the moonlight, the relationship between the two began to change from friends to lovers.
