Lin Ruoning, an ordinary young man who has just graduated and entered a big city, has gone through all kinds of strange tests in the workplace. He is surrounded by the poisonous but warm roommate Ye Ziqing, the unreliable but explosive colleague Chen Xiaofan, and he also meets Jiang Ruichen, an executive who is cold on the outside and hot on the inside, and the gentle and tough Gu Ying. The story uses flexible rhythm and humorous dialogue to show the various absurdities and warmth of urban life. In the intersection of work, love, friendship and family, Ruoning continues to resolve crises with optimism and self-deprecation, growing from a workplace novice to an urban expert. The three volumes respectively tell the story of the first experience in the workplace, the ups and downs of friendship and love, and the growth of life choices, and finally conclude with self-identity, emotional gains, and career breakthroughs.
