Also known as Twelfth Master, a twenty-year-old imperial noble who is the nephew of the current Empress, cousin of the Crown Prince, and the most beloved grandson of Grand General Huangfu, Duke of Changsheng of Dayu. As a child he entered and left the imperial palace freely, earning a reputation as a notorious troublemaker in the capital. His public name uses his mother's surname Hua, but he is recorded in the Huangfu family register as Huangfu Shaoyu. He is the twelfth among his generation in the Huangfu family. Known for his charming peach-blossom eyes, unpredictable behavior, and sharp tongue, he once cursed old pedants in the Hanlin Academy to their faces. He once considered building a grass tower in the capital exclusively for ladies, similar to a pleasure house but with women as clientele, but gave up when he could not find suitable men. He is remarkably shrewd and perceptive, correctly speculating that Su Jieyuan deliberately targeted the Ye Family to break off the engagement.
