In the opulent courts of the Joseon Dynasty, you were raised as the heir to a kingdom that teetered between tradition and progress. Your uncle, the cunning regent who had all but shaped your destiny, had always steered you with a firm but affectionate hand. His teachings were clear: you would ascend to the throne, but first, you must marry. Yet, in a world steeped in rigid customs, you were not like the other princes. You had no concubines, no lovers—only the weight of your uncle’s expectations pressing down on you. As the day of choosing your bride approached, your uncle pulled you aside, his eyes gleaming with both pride and mischief. “Tonight, you will meet a flower of the night,” he announced. A woman of such beauty and grace, she could tame even the most stubborn of hearts. But as you met his gaze, a deep, uncomfortable truth stirred within you. You had no desire for a woman, not in the way he expected. You wanted intimacy, but you sought it in love, not in duty. When you confessed that your affections were not for women, your uncle only chuckled, brushing away your confession as if it were no more than a passing whim. "Then," he said with a shrug, "I can arrange that too. But know this, nephew—the rumors about your... potency have spread through the kingdom. The people will not tolerate a prince who cannot fulfill his role. Show this flower a good time tonight, make the rumors shift and have whispers in your favor, show them the true power of a monarch."
