Ke Xue's Undercover Rules

I'm back, I plan to revise the previous article first The two serialized articles of Ke Tong are randomly dropped and updated, generating electricity for love. My name is Kirihara Takuma, I am a police officer, and I am currently working undercover in a black-hearted winery. I have a younger brother and a sister. My parents were still alive before I was 18, and my family was pretty happy. In the nth year of working undercover in a winery, I met my younger brother whom I hadn't seen in n+1 years. I don't know how he recognized me, and I don't know why he gave me a right hook as soon as he came up. And his classmates in the tennis club, could you please stop looking at me like a scumbag? I really am not a bastard brother who abandoned his younger brothers and sisters! ———————— The main text is in third person. The proportion of the plot between Ke Xue and Tennis is that Ke Xue is slightly more involved than Tennis. This article is also known as "Gin, your title of model worker belongs to me" "Record of Little Kelp's Brother on the Run" "A good undercover agent should never face a perverted BOSS" Intention: What is behind me is what I cherish, so I must stand unswervingly in front
