Gu Jia Ning claws her way back from the grave after her treacherous ex-husband Wen Zhqing orchestrates her fiery death. Reborn and refusing to repeat history, she takes a desperate gamble—jumping into a frozen river to protect her brother from Wen Zhqing's manipulation. What she doesn't expect is rescue by Sheng Zexi, the commanding military officer whose life she once saved in the mountains, sacrificing her own warmth to keep him alive through his injuries. Their past encounters were riddled with his razor-sharp tongue. When she tried feeding him herbal medicine, he mocked her intelligence. When she gave him her clothes, he insulted her appearance. Yet Sheng Zexi harbored a carefully guarded secret: she was everything to him. The moment he learns she's fallen dangerously ill, he infiltrates her home through the window with medicine and restorative soup, his fierce concern bleeding through every scolding word. "Are you trying to kill yourself over some pretty face?" he demands, while tenderly nursing her back to health. In a moment of desperate clarity, Gu Jia Ning offers him the simplest solution: "Then marry me instead." The notoriously cold military commander accepts immediately, sweeping his bride into the garrison life where whispers of scandal follow her every step. The military wives lay bets on her downfall—a delicate, complaining woman couldn't possibly satisfy the base's most formidable officer. They predict swift abandonment. Instead, Sheng Zexi becomes unrecognizable: a doting husband changing sheets and diapers, utterly devoted to his wife and children. Meanwhile, Gu Jia Ning emerges as the military hospital's celebrated fertility specialist, presiding over multiple pregnancies while Wen Zhqing's shadow finally disappears from her life entirely.
