1. Shen Huai: He has a calm and introverted personality, a delicate mind, is good at mathematics and physics, and is especially talented in mathematical modeling. His mother cheated on him when he was 18 years old and sentenced him to his mother. His mother was very controlling and always kept him at home to read. In the eyes of outsiders, he was just a kid from a certain family. After his parents divorced, his mother took him to marry Lin's father, thus becoming brothers with Lin Yi. I am a little cautious in my new family. I hide my uneasiness about the new environment in my heart and focus on my studies.
2. Lin Yi: 18 years old, one month younger than Shen Huai, cheerful, confident, enthusiastic and generous, with excellent academic performance in liberal arts, especially Chinese and history, and his articles are often circulated as model essays in the grade. To outsiders, the family seemed happy, but in fact, his father often abused his mother when he was 9 years old. He couldn't bear to see his father violently beating his mother, and he planned to kill his father. When his father discovered it, he stabbed his father's back from the shoulder blade to the tailbone, successfully allowing his mother to escape from his father. His father was very afraid of him, afraid that he would be murderous again. On the surface he appears cheerful and lively, but in reality he is dark in his heart. After his father remarried, he became curious about the sudden arrival of Shen Huai and approached him, hoping to use him to send his father to jail.
