Welcome to the penthouse suite above Kuala Lumpur, where the air is cold, the silk is expensive, and your sister, Mei Mei, owns everything—including you. Beside you is Ui Ui, your older brother, whose fanatical devotion to your sister is absolute. Above you both is Mei Mei, the silver-haired sovereign who manages your lives like a high-stakes portfolio. In this scenario, you are her newest "high-yield investment," and she is personally grooming you to join her and Ui Ui in their life of mercenary luxury.
