Child Marriage: She Attracts the Billionaire Uncle Down to the Mortal Realm

Lu Jianshen, the second son of China's wealthiest man, Lu Yuanting, is a cold, aloof business prodigy groomed to inherit the family empire. At age ten, he is summoned from school in the United States to attend the birth of his betrothed, Hua Rui, the youngest daughter of his father's close ally, Zaitian Hua of the Huatian Group. The two families had arranged a marriage between their children decades ago, but when both firstborns were boys, Madam Hua vowed to give birth to a daughter to fulfill the promise. When Jianshen first meets the infant Rui, he is unimpressed by her appearance and distressed when she wets him, immediately seeking to return to America. Despite his reluctance, his mother confirms the engagement is official, and he is forced to accept the arrangement.

Eight years pass. Jianshen, now eighteen, is a legendary figure in the business world, possessing a master's degree and managing his father's mergers and acquisitions. He remains indifferent to romance, viewing his childhood betrothal as a mere formality. At his coming-of-age ceremony, he encounters eight-year-old Rui, who has transformed into a delicate, beautiful girl with a distinctive peach blossom birthmark on her forehead. When she drops and breaks her sugar figurines, Jianshen quietly repairs them and promises her new ones, an act that marks the first time he shows genuine softness. He secretly begins collecting photos of her growth, maintaining a distant but watchful presence from afar.

Another decade passes. Jianshen, now twenty-five, returns to China to host Rui's eighteenth birthday and engagement ceremony. He has meticulously prepared for this moment, selecting a rare pink diamond engagement ring and compiling a private album of her life. Rui, however, is unaware of the engagement's immediacy and feels like an interloper, especially after learning that Jianshen has a close childhood friend, Liu Ruyan, who harbors feelings for him. During the ceremony, Jianshen publicly declares Rui as his fiancée and places the ring on her finger, shocking her. Despite her initial resistance and shy demeanor, she accepts the engagement, though she continues to address him as "Little Uncle," maintaining an emotional distance.

As the newly engaged couple begins to interact, Jianshen reveals a protective and caring side, surprising Rui. He cancels a trip to the United States to spend time with her, takes her to eat at a barbecue restaurant, and shields her from the sun with his body. Their relationship slowly warms as they visit a sugar figurine shop, where Rui proudly shows him her artistic designs. However, complications arise with the introduction of Xie Mingchen, Rui's art teacher and a figure who has silently loved her for five years. Xie Mingchen watches from the sidelines as Jianshen and Rui grow closer, his affection restrained by his role as her elder and teacher.

The story follows the gradual development of Jianshen and Rui's relationship as they navigate family expectations, social pressures, and the lingering presence of past suitors. Jianshen, once indifferent to love, finds himself deeply invested in Rui's happiness, willing to change his schedule and priorities for her. Rui, in turn, begins to see past his cold exterior to the devoted man beneath. The narrative explores their journey from an arranged childhood betrothal to a genuine romantic connection, set against the backdrop of China's elite social circles and powerful business dynasties.
