The Lu family of Yongcheng Marquis Manor are trusted ministers close to the emperor, with a distinguished lineage, but a curse hangs over them. Rumor has it that their whole clan will be wiped out in the near future. The only way to break the curse is for a descendant to marry a Jiang woman and have a child carrying Jiang blood.
As it happens, Jiang Lingyi claims that when she was a child, she was rescued by Lu Huai, the heir of the Lu family, and is determined to marry him.
Jiang Lingyi is beautiful, with a voluptuous figure, and is undoubtedly the most beautiful woman in the capital.
Lu Zhun falls in love with Jiang Lingyi at first sight. The two are smitten with each other and quickly agree to marry.
But a month before the wedding, a foreign tribe invades. Lu Zhun leads the army into battle and returns victorious, but suffers a serious injury to his lower body. He may not be able to consummate the marriage for some time, and no one knows when he will recover.
With the wedding date drawing near, the Lu family has no choice but to have the second son, Lu Yan, stand in for his elder brother and marry the bride.
Lu Huai and Lu Yan are twins. Lu Zhun is gentle as jade, while Lu Yan is carefree and unruly. Their temperaments differ, but their faces are almost identical.
Anyone who isn't close to them would struggle to tell them apart.
After marrying into the Lu family, Jiang Lingyi finds that her husband's temperament seems very different from before. He is not only cold toward her, but often verbally bullies her. But mindful of his life-saving kindness, she puts up with everything and only tries harder to please him.
At last, after he accidentally drinks deer-blood wine and she helps him through its effects, their relationship begins to change.
He continues to "bully" her, just in a different way.
Her husband is exceptionally endowed. Although Jiang Lingyi is often worn out at night, their life together can still be called sweet and loving.
Until the day the rumored "younger brother-in-law," Lu Yan, returns. While bringing her husband a pot of soup, she happens to hear the physician advise him: "The heir has been frail since childhood, never as strong as other men. Now he's been injured on the battlefield as well. Though he has undergone treatment, he may still be able to father children, but I'm afraid he won't be able to perform well in bed. He must keep taking his medicine on schedule."
Her husband was frail since childhood? Jiang Lingyi's beautiful eyes widen in shock. Then who was the man beside her in bed, with his terrifying stamina, who kept her up all night?
She feels her legs give way and is about to fall when an arm suddenly reaches out from the side and catches her around the waist. She looks up to see her husband's lookalike younger brother. A faint smile plays on his handsome face, but his gaze is strangely burning. "Sister-in-law, be careful."
They are supposedly meeting for the first time, but the heat at her waist and the breath brushing her ear are terrifyingly familiar!
