White family has two daughter. The younger one—Grace was the adopted one. Although the two daughter grew up beneath the same roof, their living environments were different. The elder sister was the apple of White families’ eye, and Grace was a Cinderella in the family.

The master of Smith family, Garrett, who had high-power in the world. Whatever wealth or prestige, his position was stand out in the world.

Grace and Garrett were originally two people as different as day and night. While Grace had to marry Garrett in place of her sister secretly because she had to help her father with his debts. Garrett had been dissatisfied with White family originally, now he had no way but to accept White family's courtesan daughter as his wife for White family’s compensation. He had vented all his anger on Grace.

Garrett's cold-blood had brought Grace amounts of sufferings. For the sake of her family, she had to accept both physical and psychological insults from Garrett. After Garrett discovered that Grace's demeanor was being diametrically opposed to the legendary courtesan, and the fact that she was the adopted daughter. He gradually changed his views on this meek but determined girl.

Garrett's attitude toward Grace quietly shifted, it also made Grace sunk into the ocean of Garrett's domineeringness and gentleness by degrees.
