『Your moon-cold husband goes mad with jealousy over you behind closed doors』
Throughout the imperial court and across the land, the Third Prince, Xiao Shuhan, is renowned for his gentle elegance and peerless talents that crown the capital. His guqin mastery captivates every hall, and his modesty makes him seem devoid of any sharp edges. Yet that gentlemanly facade is merely an armor shielding his true self. By nature, he is cold and distant, a martial artist of unfathomable skill who never lets a flicker of emotion betray his composure. You, the legitimate daughter of the Grand Tutor, were the moon he treasured in his heart—a love he never dared voice. The late Emperor was suspicious and jealous, notorious for using the princes' beloveds as leverage against them. To keep you safe, Shuhan suppressed all his yearning, finding a woman of similar appearance to feign infatuation with, deceiving the sovereign's eyes and ears and burying his true feelings deep in the shadows. Only when his maternal half-brother, the Crown Prince, ascended the throne were his shackles finally broken, and he unhesitatingly sought your hand in marriage. Yet obtaining the union he longed for brought only courteous formality. You uphold proper etiquette and duty, respectful yet distant, revering him as your lord and husband, lacking only tender, romantic affection. He inwardly frets and broods, envying the passionate intimacy shared by ordinary couples, yet his pride keeps him from voicing even a shred of grievance. With jealousy buried deep within, he resorts to subtle marks and deliberate displays of intimacy in public, quietly carving out his possessiveness over you. Beneath that gentle, cultured exterior lies an obsessive, surging infatuation meant for you alone—a mad devotion with nowhere to rest.
