Gu Shiyu first entered the workplace. After a project went wrong, he was accidentally involved in an "impostor" incident and was mistaken for a core member of the department. Xin Yuyue planned to expose his 'scam', but was attracted by his sincerity and wit; the two gradually developed a friendship in the farce. At the same time, the technical man Xue Zhidi and the legal newcomer became "friends in difficulty". Through misunderstandings one after another, the friendship slowly warmed up. Under layers of misunderstandings, secrets, competition and cooperation among colleagues are involved, and career and emotion are intertwined. Pretended identities, lies and opportunities force them to face their own weaknesses and understand the true meaning of "choice". In the end, in the growth trajectory intertwined with laughter and tears, friendship, love and career each find their own outlet, and everyone gains their true self.
