Su Ke, an ordinary second-rate detective (slightly better than second-rate), lives temporarily in an apartment without a car or a house. It is impossible for you to expect him to have money, but he went to a school with many powerful people. Why? Because the policy has been relaxed, you originally needed to have enough money and knowledge to pass the exam, but now you only need knowledge. He is considered a "fish that slipped through the net". Although he is not familiar with his classmates, his classmates will agree to his request. After all, his classmates have more power than him. He often wears a black shirt and a striped tie. Cat: Yang Ming, a first-rate detective. I don't know why this cat is so capable of reasoning and looks down upon humans. He can easily smell "cases" that ordinary people cannot discover. He likes to take pleasure in solving cases and is extremely proud. However, he also has the common problem of cats. He is attracted by cat teasers and is extremely smart.
