When a Dainty Capitalist Heiress Marries the Military Compound's Devil

Xu Suyu, an eighty-year-old woman, signs divorce papers on her deathbed after her husband Han Shumo reveals their sixty-year marriage was merely a transaction to repay a debt of gratitude. As he dies, she regrets the illusion, only to awaken sixty years in the past on the very day her future father-in-law is pressuring Han Shumo to marry her. She realizes she has been reborn and now has the chance to alter her tragic fate. In her previous life, Han Shumo had reluctantly agreed to marry her to save her from reeducation, but this time he immediately refuses, declaring his love for Qin Wanqiu. Xu Suyu understands that Han Shumo has also been reborn and is determined to escape the deceptive marriage she endured for decades.

With only three days to find a husband to protect her from her family's political downfall, Xu Suyu faces a desperate situation. Commander Jiang Zhunián, a decorated veteran and the grandfather of Jiang Sun, arrives unexpectedly. He reveals that Xu Suyu’s grandfather once saved his life and offers to marry her to his unruly, arrogant grandson, Jiang Sun, as a means of protection. Despite Han Shumo’s refusal and the warnings of those around him about Jiang Sun’s dangerous reputation, Xu Suyu accepts the proposal. She sees an opportunity not only to survive but also to save Jiang Sun from his doomed fate in her previous life, where he was executed for hooliganism, and to clear her grandfather’s name.

Upon moving into the Jiang residence, Xu Suyu encounters the volatile Jiang Sun, who is initially hostile and dismissive. However, she establishes boundaries with calm authority, refusing to be bullied by his temper while simultaneously showing him unconditional trust. When Jiang Sun’s stepmother, Sun Rou, and half-brother, Jiang Mingguang, attempt to frame him for assault, Xu Suyu deftly exposes their scheme, forcing a public apology and securing Jiang Sun’s innocence. Her intelligence and composure begin to shift Jiang Sun’s perception of her, transforming her from a fragile outsider into a formidable ally.

Tensions rise when Han Shumo and Qin Wanqiu encounter Xu Suyu at a supply cooperative. Han Shumo attempts to manipulate Xu Suyu into giving up clothing he wants for Qin Wanqiu, but she firmly refuses, asserting her independence. Jiang Sun intervenes aggressively, defending Xu Suyu’s dignity and publicly declaring their engagement, which shocks the onlookers and humiliates Han Shumo. Later, Cao Meiru, Han Shumo’s mother, attempts to lure Xu Suyu back into the Han family by offering money and false kindness, but Xu Suyu and Jiang Sun repel her schemes together, solidifying their alliance.

Xu Suyu recognizes that Jiang Sun’s rebellious behavior stems from trauma and a lack of direction. She decides to guide him toward a better future, encouraging him to study and excel so he can surpass Han Shumo and avoid his tragic end. Their relationship evolves through a series of confrontations and moments of vulnerability, including a charged encounter where Jiang Sun tests her boundaries, only to be met with her witty and assertive response. As they navigate the complexities of their arranged marriage, Xu Suyu remains focused on her dual goals: ensuring her own survival and rewriting the fates of those who wronged her in her past life.

The story follows Xu Suyu’s strategic maneuvering within the military compound as she builds a new life with Jiang Sun. She balances her role as a protective granddaughter-in-law to Commander Jiang with her efforts to reform Jiang Sun’s behavior. Meanwhile, Han Shumo and Qin Wanqiu’s relationship faces underlying tensions due to family disapproval and societal pressures. Xu Suyu’s transformation from a passive victim to an active architect of her destiny sets the stage for a confrontation with her past, as she seeks to prove her grandfather’s innocence and secure justice for those who suffered under the political turmoil.
