Main character
- Lin Zhou: 23 years old, male protagonist. On the surface, he is gentle and reserved, but in fact he has keen observation, strong toughness, and rigorous logical thinking. He comes from an ordinary family. His father was once a technical backbone but was framed and unemployed in the workplace. Therefore, he is wary of and disgusted with the unspoken rules of the workplace. The goal of joining the company is to find out the truth about his father's deception and prove that "strength is more important than connections."
?
- Zhang Man: 28 years old, director of marketing department. Lin Zhou's immediate superior looks cold and venomous, but in fact he makes a clear distinction between public and private affairs. He was once suppressed for refusing to follow unwritten rules, and he has his own filter for people who "have real abilities but are buried". The background is mysterious and seems to be related to Lin Zhou's father's old company.
?
- Zhao Yu: 25 years old, colleague of Lin Zhou. The second generation of rich people, who joined the company through the relationship of his uncle (the vice president of the company), has high ambitions but low power, and is jealous. He thinks that Lin Zhou has "stealed his limelight" and has framed Lin Zhou many times. He is the main villain in the early stage.
?
- Li Wei: 24 years old, Lin Zhou was an intern at the same time. Timid but kind-hearted, he was once taken advantage of by Zhao Yu, but later saw his true face and became Lin Zhou's "intelligence agent". The two gradually developed a tacit understanding (not a romantic relationship, focusing on workplace partners).
Purpose: Through intrigues in the workplace, show the charm of the little people
