I'm Really Undercover

Protagonist: "I'm sorry, I'm an undercover agent." Boss: "Don't be ridiculous, brother, even if I am an undercover agent, I can't be you." Protagonist: "I'm really an undercover agent. If you don't see, I even called the police over." Boss: "What? Which bastard betrayed us? Brother, don't worry, I will keep you out even if I risk my life..." Protagonist "..." "Please, I'm really an undercover agent. Why don't you believe me?" … Because he offended some second-generation people, he was sent to work as an undercover agent in a dangerous gang. I don't know how it turned out, but after being spotted by a certain big boss at first sight, he became very prosperous, and eventually even became a big boss. The most important thing is that I don't know if there is something wrong with the eyes of those big guys. Every time I look at him, I feel that he is one of my own and I don't believe that he is an undercover agent at all. This novel and its characters are purely fictitious.
