The male protagonist should be a prince or something, but he was sent out of the palace when he was young and sent to the female protagonist's house. It seemed that many of the female protagonist's family were similar to adopted sons. The female protagonist was very cute when she was young, but her father died quite early and needed her to support the family. Later on, she became a little naughty on the surface and never explained her actions to others, but she was still very good on the inside. She remembered that the male protagonist seemed to have a good relationship with one of the female protagonist's maidservants, but that maidservant did not want to be inferior to others, so she married an old man and became a concubine. Everyone thought that it was the female protagonist who forced her, but the female protagonist did not explain. Later, the servant's husband died and he was chased out. He met the female protagonist and the others. Everyone wanted the servant to return to this house, but the female protagonist did not agree. In the end, she wanted to chase the male protagonist and the concubine out together. In the end, it was the female protagonist's other servant girl who told the truth. Only then did everyone understand. In the middle, the female protagonist seemed to have gotten pregnant once, but the child was aborted. However, no one knew about this. Every year on the child's death anniversary, the female protagonist would ask the male protagonist to pay his respects to the child. The male protagonist never knew that he was paying his respects to his own child. Later, it seemed that the emperor also ordered the female lead to enter the palace. It was only after the male lead entered the palace to see the emperor that it was settled.
