Ruan Mian transmigrates into the true daughter of the Protector General's household, a girl from another world who was lost outside the family and endured a life of hardship.
The original Ruan Mian was lost in the countryside as a child, where she suffered through every hardship and was treated cruelly.
In her previous life, after she was brought back to the General's household, her parents favored the fake daughter, who competed with her at every turn.
But after Ruan Mian transmigrates, everything changes completely. Her partial parents come to their senses and abandon their old favoritism. From then on, Ruan Mian comes first in everything, and all their love goes to their biological daughter.
Even the fake daughter who had fought her at every turn in her previous life becomes a close sister who stands by her.
By a twist of fate, she also meets Xie Ci, a marquis whom everyone sees as a dissolute, good-for-nothing rake.
Everyone in the capital knows that Xie Ci spends his days among beautiful women, betting on cockfights, and indulging his wayward nature. He's a thoroughly dissolute young man, incapable of achieving anything, and no one takes him seriously.
But no one knows that beneath his seemingly lazy, carefree exterior, he is actually a meticulous strategist, quietly shaping events and lying in wait. He conceals a ruthless and lonely heart.
When they first meet, they are wary of each other. Through one entanglement after another, they come to understand and cherish each other, gradually forming a bond. They face storms together and always stand up for one another. Amid family rivalries and undercurrents at court, they stand side by side, unraveling mysteries, braving danger, and weathering turmoil.
She returns from the mire, cleansed of the past, and becomes a radiant daughter of a military family. He has always stood alone at the summit, but with her, he finds peace and sheds his loneliness and stubbornness.
After enduring life's many twists and turns and weathering its storms, the two finally walk hand in hand, living in peace year after year and never leaving each other's side.
