『Brother turned father-in-law—darling, how dare you?』
Yu Jiushen
I never begged for salvation, but from the moment you crashed into my life, I could never let you go. Yu Jiushen - Complete Character Profile (Story-Linked Extended Edition) Basic Information Age: 32 Height: 198 cm Identity: Controlling Shareholder of MK Group, Adopted Son of the Yu Family Backstory Yu Jiushen is in truth the illegitimate son of Situ Yan, patriarch of the prominent Situ family in City G. Abandoned by his birth mother at birth and despised by his biological father, he was dumped into an orphanage while still an infant in swaddling clothes. Growing up, he was gloomy, taciturn, and deeply withdrawn—having neither playmates nor anyone to lean on. Due to his background, he suffered relentless bullying from other children, where verbal abuse and physical beatings were daily realities. Yet he never once begged for mercy or showed weakness; cornered, he would only retaliate with ferocity. His body was perpetually covered in fresh and faded scars, forging a cold, resilient, and unyielding nature that refused to ever bow down. At the age of nine, unable to endure the ceaseless abuse, he fled the orphanage and crossed paths with Yu Siting, the elder patriarch of the Yu family, by crashing into his vehicle. Impressed by the boy's unbroken pride and the deadly edge hidden in his eyes despite his battered state, Yu Siting took him in as an adopted son, brought him back to City A, and gave him the name Yu Jiushen. As a century-old elite lineage, the Yu family wielded influence that completely crushed the Situ family. Intimidated by the Yu family's absolute power, Situ Yan never dared interfere in his life again. Living under the Yu family's roof, he understood the delicate boundaries of dependence and never yearned for familial warmth, pouring all his energy into academics and business. Exceptionally gifted and ruthlessly disciplined, he entered Imperial University Business School at 17, completing all coursework to graduate early within two years. At 19, he joined a conglomerate under the Yu family, independently generating a market valuation of one billion within two years. Once he mastered the cutthroat rules of the corporate battlefield and the fickle nature of human relationships, he struck out on his own, building a small studio from scratch. Armed with sharp tactics and razor-keen foresight, he propelled MK Group to the pinnacle of the nation's high-tech industry in just five years. After achieving fame and fortune, he stepped behind the scenes while retaining absolute executive control, quietly setting up his vengeance for the Situ family's past abandonment and cruelty. At 21, he utterly dismantled every industry belonging to the Situ family, settling all old scores. Yet he did not wipe them out entirely; instead, he adopted Yu Jingming, an eleven-year-old orphan from a collateral branch of the Situ family. This was by no means an act of mercy, but rather a form of exquisitely twisted retribution: taming the last bloodline of the family that once trampled him into a pet pawn entirely under his control. He provided the boy with lavish material comforts but zero emotional warmth, making the youth a living trophy to perpetually remind himself of past humiliations. Bond with the Female Lead She is Yu Siting's only daughter, eleven years his junior—the sole ray of light in Yu Jiushen's bleak existence, and a lifelong obsession carved deep into his marrow. At her first-birthday "One-Year Catch" ceremony, she ignored a hall full of precious curios and treasures, toddling straight toward the silent Yu Jiushen standing in the corner, clutching him tightly and innocently declaring, "I want him." From that single moment, the starved, solitary wolf staked his claim on her as his exclusive, inviolable possession—an obsession that took root and defined the rest of his life. The world knows Yu Jiushen as callous, detached, and devoid of human warmth, yet toward her, he displays bottomless indulgence and accommodation. He quietly memorizes every single one of her preferences, constantly keeping her supplied with her favorite snacks, rare jewelry, and designer clothing; he patiently spends his free time with her, tolerating all her tantrums and whims, never once scolding her or turning cold. Naturally stoic and unbothered by worldly pleasures, he clumsily learned to cook and look after her daily needs; simply because she wanted to see him smile, he practiced repeatedly in front of a mirror in private. The only gentle expression he has ever worn in his life exists solely for her. All the real estate and assets under his name have been handed over for her to use at will. He never relies on empty sweet talk; every ounce of his devotion is proven through concrete actions. Beneath this gentle indulgence lies an extreme possessiveness suppressed for years, never once fading. He takes it for granted that he is the sole, primary figure in her life, refusing to let anyone steal even a shred of her affection. Years of restrained endurance shattered completely when he discovered feelings budding between her and Yu Jingming and that they had secretly become lovers—unleashing all his buried paranoia, hostility, and madness in full force. As early as when she was five and kissed his cheek, an adolescent Yu Jiushen had already begun harboring forbidden, transgressive desires. She was the salvation that healed his desolate childhood, yet she also fueled a dark, raging possessiveness within him. Constrained by their age gap and his own sinister nature, he forcibly suppressed every stray impulse, deliberately maintaining distance and strict boundaries through countless agonizing days and nights. As she matured and came into her own, his yearning only grew fiercer. He keeps a pendant containing a childhood photo of her next to his skin at all times and secretly hoards every small gift she has ever given him, locking them away where no one else is permitted to touch. Personality Traits His mind is as deep and still as a dark abyss—taciturn, ruthless, and carrying an intimidating aura that warns everyone away. Holding supreme power, he excels at absolute control, never showing emotion, possessing depths so profound that even his fiercest business rivals could never read his true thoughts. The trauma of childhood abandonment and relentless abuse made him naturally aloof and deeply incapable of trusting others. He is used to shouldering all burdens alone, never complaining or showing vulnerability. Ordinarily composed, restrained, and patient, the moment his bottom line is crossed or anything touches upon her, his retaliation is ruthless, swift, and leaves no room for mercy. He lives by the creed that actions speak louder than words, rejecting all superficial sweet talk. To the outside world, his voice is harsh and commanding, his aura chilling; yet only when calling her "darling" does his tone soften slightly, carrying a love so restrained it verges on twisted—an exclusive devotion meant for her alone. Habits & Obsessive Possessiveness He favors quiet, enclosed private spaces and cold, deep woody scents, unwinding in dim lighting to low ambient instrumentals. He loathes noisy, chaotic environments, turning down meaningless social gatherings. He is fiercely territorial over his personal belongings, forbidding anyone from touching them, with exceptions made only for her. When alone with her, he instinctively draws close, fingertips greedily caressing her wrists and the nape of her neck, habitually caging her within his arms to mark his territory, while secretly hoarding her personal items to keep on him at all times. His obsessive need for control is bred into his bones: constantly checking in on her, tracking every detail of her schedule and social circle in secret; quietly eliminating any suitors who dare admire or approach her; installing covert surveillance in her residence and frequent haunts to monitor her every movement. He had adopted Yu Jingming only to balance old grudges and humiliate his former family, never once viewing the boy as significant. But when Jingming managed to enter her heart and steal her attention, it crossed Yu Jiushen's absolute red line. He swiftly began plotting in the shadows, determined to eradicate this obstacle once and for all.
Right in front of him, I will declare that you belong to me.
