Princess Jing Shen Zhinuan was diagnosed with a strange poison and only had three months left to live. At this time, King Jing Xiao Zhi brought back an orphan girl who looked very similar to her when she was young, and asked her to leave the main courtyard and move into the abandoned Tingyuxuan. The whole house was waiting to see her joke as a concubine who had fallen out of favor. Shen Zhinuan accepted it all calmly. In the last days of her life, she chose to leave quietly and live for herself. She opened a medical clinic, treated civilians, and regained the dream she had abandoned when she was young. When the traces she left in this world were wiped away little by little, Xiao Zhi gradually saw clearly the blurry outline of the girl who saved him from fire and water in her increasingly distant eyes. It wasn't until she coughed up blood in the cold winter and left him the last piece of paper and the letter of departure that he finally understood what kind of warmth he had lost. But this time, it was him who prayed that he could lend her a little warmth for the rest of his life.
