Su Mengdie has lived for eighteen years before learning that she is the Su family's real daughter, lost to them long ago.
Returning to the wealthy family brings no warmth or affection, only endless exploitation and humiliation.
The fake heiress, Su Rou, is spoiled and domineering, taking everything from her, even forcing her to take her place in an arranged marriage.
Everyone in the city knows that Li Chenyuan, the powerful head of the Li family, is sinister and brutal, disabled, and a curse on his wives. His three previous fiancées all died under mysterious circumstances, making him someone everyone avoids.
To curry favor with the Li family, the Su family coldheartedly shoves her into the fire, forcing her to marry in her sister's place and bring good fortune to her husband.
On their wedding night, she cowers in a corner, certain she is doomed.
But the man sheds his cold demeanor and gently wipes away her tears. “Don't be afraid. I'm here.”
Only later does she discover that his reputation for brutality and bringing death to his wives is all a facade. His icy indifference is reserved for everyone else.
He stands up to her cruel relatives for her, silences the rumors for her, and gives her all the tenderness he has.
The Su family regrets its actions and kneels, begging her to come back;
The scheming fake heiress is thoroughly face-slapped by him;
The whole world knows that the only one in President Li's heart is his little substitute bride.
With President Li doting on her, Su Mengdie tears into her enemies, turns her life around, and ultimately becomes the wife of the Li family, envied by all.
