Don't abuse me, my dear prince. I'm marrying your elder brother (MTL)

As Lou Jin's concubine who warms her bed, Sui Sui has always been conscientious in her duties, taking it as her responsibility to protect the Huainan Palace and welcome the grandson as soon as possible.
　　But everything changed after the rebels attacked the city. The man who once cherished her tortured her over and over again and punished her by all means.
　　He forced her to the bed and kissed her fiercely, pinching her waist and leaving bruises all over.
　　She cried and begged for mercy, but the man became more and more crazy. Day by day, she could not die and lived in a daze all day.
　　Until the appearance of the warm and spring-like eldest son Lou Jun, she rekindled her hope of life.
　　The eldest son secretly fixed the leaky roof for her;
　　she burned her throat, and the eldest son found the only ice jade in the world to heal her;
　　she was slandered as a thief by the county magistrate's daughter, and the eldest son helped her out and proved her innocence;
　　she was bullied by the concubine who suffered from asthma, and the eldest son planted a yard of willow trees to let her vent her anger with flying catkins;
　　the maid who bullied her was beaten with a stick, and the eldest son sent away all the doctors in the palace and the doctors within a few miles, and the maid banged her head against the wall in pain...
　　A few years later, the truth came out, she had married the marquis Lou Jun, and became Lou Jun's favorite little wife.
　　Lou Jin regretted it and cried from Huainan to the capital: "Sui Sui, I know I was wrong." Sui
　　Sui: "..."
　　Lou Jun: "Get lost, this is your sister-in-law."
　　The person who favors her may be late, but he will definitely show up to protect her from the wind and rain for half a lifetime.
