She was a maid. He was the heir to a noble title.
The legitimate daughter told her to seduce him so she could make room for herself.
So she did.
But the story didn't go the way the legitimate daughter had planned.
She made him remember her, care for her, and become unable to live without her.
She helped him deal with his stepmother's persecution, foil political schemes, and take the position of Minister of War.
The legitimate daughter was so furious she smashed a cup, and the stepmother ground her teeth with hatred.
But neither of them could lay a finger on her.
Because he stood in front of her and said, “Hurt her, and you hurt me.”
Later, everyone in the capital knew that the aloof Heir Xie doted on his wife, a former maid, as if she were the most precious person in the world.
Someone asked him why.
He said, “She taught me more than you could learn in a lifetime.”
