As a top elite returning from Wall Street, Lin Zhixia has only two creeds in life: efficiency and KPI. On the first day when she landed as the director of the marketing department of a large domestic factory, she looked at the group of "old fritters" who were dawdling in the department and had only one thought in her mind: all employees would be laid off. The good news is that she holds great power, acts resolutely, and is determined to rectify the workplace. The bad news is that before she could take any drastic measures, she was "sanctioned" by the senior manager in the department named "Lao Gu". Lao Gu, thirty-eight years old, soaks wolfberries in a thermos cup. His workstation is always neat and tidy, and he is always calm when things happen. When Lin Zhixia stayed up until three o'clock in the morning for the bidding plan, Lao Gu handed her a cup of warm honey water: "Mr. Lin, the body is the capital of the revolution. I have polished the plan and closed the logic. Take a look." Lin Zhixia: "..." When Lin Zhixia faced Party A's difficulties and was so angry that she wanted to slam the table and leave, Lao Gu stood in front and said the harshest words in the gentlest tone, making the other party speechless. Lin Zhixia: "..." There is a rumor in the workplace circle: The devil girl who has returned from overseas is probably going to be manipulated by Lao Gu. Lin Zhixia didn't believe in evil at first, until one day when she was working overtime and there were only two of them left in the office, Lao Gu unbuttoned the cuffs of his shirt, revealing a strong forearm, and looked at her deeply: "Mr. Lin, I understand all the rules in the workplace, but I want to talk about... Personal rules." Breaking the identity gap in the workplace, it turns out that the uncle who only knows how to make tea is the most advanced hunter.
