People in Kexue: I Became the Boss of the Police Academy Team

I didn't want to read it after I saw the beginning. The timeline doesn't match up at all, right? Did the author arrange the sequence of Jingguang's exposure and Hagi's death in the wrong order? I barely read two chapters and I don't know what to say. Jingguang is not someone who would show off his sharpness so obviously. Zo is not stupid either. He answered Hiro's call in front of Gin and Aunt Bei. In addition, even Zo's cooking skills were taught by Jingguang, but it turns out that Jingguang can't cook? Do you still envy Jinpei? Comparing them, Matsuda is the one who can't cook, right? Also, in the name of the police academy unit, before I write about being a big boss here, I would like to ask you to search the difference between the police academy unit, the Metropolitan Police Department, and the National Police Agency. Thank you very much. The subject matter is not objectionable at all. Can you understand the difference?
