Synopsis:The brilliant and sharp-minded Gu Jinyu, the true heiress of Bailong City who has been disguised as a man since childhood due to the old city lord’s lack of heirs, is sent on a mission to infiltrate the mountains in search of a treasure map. Meanwhile, the seemingly naïve and sweet Bai Yunxi of Black Tiger Fortress, whose real personality is quite silly and gullible, goes down the mountain to “snatch a groom” in order to fulfill her late father’s wish and inherit the family business. By a twist of fate, Gu Jinyu is kidnapped up the mountain and forced into marriage, becoming Bai Yunxi’s “husband.” The two strike a deal to pretend as a married couple, thus beginning a hilariously chaotic adventure of mistaken identities and comedic mishaps. However, the fortress turns out to be a failing enterprise on the brink of collapse due to poor management. To make matters worse, the ambitious second-in-command is eyeing the throne, a foolish strategist constantly stirs up trouble, and unscrupulous merchants add fuel to the fire. Luckily, Gu Jinyu is a business prodigy. Together with Bai Yunxi, she restructures and revitalizes the fortress, turning its fortunes around while thwarting multiple conspiracies. Along the way, they develop a deep “feudal-era sisterhood bond.” Yet, once Gu Jinyu’s true identity is revealed, tensions erupt between Bailong City and Black Tiger Fortress. With war looming on the horizon, the fate of their relationship hangs in the balance.
