Project director Shen Du manages the special fund for Boss Chen's birthday banquet. Cousin Zhao Qiming, trying to save face by holding a luxury engagement banquet and unable to pay the bill, pressures Shen Du to misappropriate the special fund, which is refused. He then teams up with his mother to apply pressure and steal the stored-value card, but fails because the card requires authorization from the custodian, and falsely accuses Shen Du. Shen Du asks the supervisor and Boss Chen to testify on speakerphone, exposing the lie. Zhao Qiming is left with a 72,000 bill that no relatives are willing to help pay, and his fiancée Lin Yue breaks off the engagement. Back at the company, Zhao spreads rumors and alters the project proposal. In the department meeting, recordings, chat logs, and intern Xiao Xia's testimony expose the truth, and Zhao receives a disciplinary warning and a reassignment. Shen Du holds his bottom line, earns the boss's trust, continues managing the funds, and successfully organizes the birthday banquet.
