Marrying into a Marquis's Household

Three years ago, on the day they were to be betrothed, Lu Si abandoned Gu Mingshu to clear the name of his childhood sweetheart's family. That was when she learned that he had deceived her from beginning to end! He had only used her! He had never truly loved her.

After Lu Si left without a word, Gu Mingshu's reputation was ruined and her family cast her aside. Overnight, she went from their biological daughter to an adopted one. Later, word spread that Gu Mingshu had gone mad.

Three years later, the once dashing Third Miss Gu has become a sickly young woman who coughs every few steps. To protect the family's reputation, the Gu family plans to marry her off in haste.

But on the day of the betrothal, Young Marquis Lu, who had been away at war for three years, suddenly returns to the capital. His arrival throws everyone's plans into disarray.

Lu Si asks to marry Gu Mingshu, and an imperial decree leaves her no choice but to agree.

He thinks he has finally married the woman he has longed for throughout those three years. But when the truth comes out, Gu Mingshu tells him to his face that she had been using him all along and had never trusted him. Only then does he belatedly understand how deeply he hurt her three years ago.

Afterward, he willingly lets her use him, asking only that she spare him a little more of her attention.

Even knowing that she wants to overthrow the imperial order, he can only smile and pave the way for her.

The free-spirited Young Marquis Lu falls for Gu Mingshu's bold, radiant nature the first time he meets her. But three years later, seeing her weak, helpless, and drained of life makes Lu Si afraid for the first time that he might lose her.

After marrying her, he tries his best to make amends, but all Gu Mingshu gives him in return is distance and indifference. Even when he offers her his whole heart, she acts as if she doesn't see it.

Later, he comes to understand that beneath her fragile appearance lies an ambition to manipulate the currents of power and scheme for control of the realm.

But he is willing to submit to her.
