Chen Nianzhao, a modern social animal, became a fourteen-year-old girl in the West Beijing Station. Su Jue, thirteen years old, was said to be the son of a deceased friend and had been fostered for two years. Cold and delicate, cherish words like gold. With her sharp eyes, she had already noticed that something was wrong with this "younger brother": his homework was all wrong, so he was pretending to be stupid; his luggage was packed with murderous intent, so he was pretending to be poor. She saw through it but didn't reveal it, and even gave him a code name - Little Ancestor. She took him to school, broke cooking cakes, helped victims of disasters, fought against slanderous scholars, and lived a lively life. He looked on with cold eyes, thought she was superficial, and called her a liar, but he clearly remembered every crazy thing she said. During a mountain bandit robbery, she knew she should run away, but she turned back to the rocky slope and took care of him all night - the man who had been hiding from the kindness of the world for fourteen years reached out and took the hand offered to him for the first time. She was tempted and bravely confessed. But he wanted to leave: go to Beijing to take the exam, gain fame, and get closer to the center of power that destroyed his family. When parting, he said heart-wrenchingly: "You just mistook other people's faces and settled on mine." When the apricot blossoms bloom, disaster strikes. Before her parents died, they gave her a marriage certificate: go to Beijing and join the Wen family of Shang Shu, where there was a baby-like fiancé whom she had never heard of - Wen Yushu. On the river, she broke the tokens into pieces, threw them into the water, and buried them together with the little sentiment. Beijing, she is here. Not to surrender to anyone, but to collect a blood debt.
