"Updated, don't watch" [Double C + Cookies + Mutual Redemption + Marriage First, Love Later]
(The introduction is not very good, you can read the text first)
As the eldest son of a prince, Zhao Hexiao has always lived in the shadow of his brother who died young. His father never recognized his efforts, and his mother was immersed in longing for him all day long. He worked hard since childhood, just to become a qualified eldest son, but when he did an errand and clearly did it well, but still received his father's disapproval, Zhao Hexiao finally became disheartened.
When he gave up on himself, he met Yun Niang, a miserable woman who was sold into a brothel by her biological father. For unknown reasons, he rescued her and secretly placed her as his concubine.
At first, he only thought of her as a cat fostered in another house, teasing her for fun in his free time, but as they got along day after day, Yun Niang's tenderness and sincerity gradually came into his heart. Seeing that she would never see the light of day due to her status, Zhao Hexiao suddenly felt that he should fight for her.
