Lin Ziyu, a simple, kind-hearted and righteous girl, was lucky enough to join the Film Public Relations Company, but unfortunately she had a grudge against her genius boss, the wealthy Fan Shuchen. They had frequent conflicts at work and lived in fear. Unexpectedly, from the day Lin Ziyu joined the company, Film Public Relations had repeated commercial leaks. Fan Shuchen's focus of suspicion was on Lin Ziyu, but in the back and forth with Lin Ziyu, the two admired and loved each other. Fan Shuchen's other three best friends also had successive encounters with Lin Ziyu, and each had their own speculations about Lin Ziyu's identity, which made Fan Shuchen even more confused. As the public relations crisis became increasingly apparent, Fan Shuchen's opponent Luo Zongliang surfaced. It turned out that he was the creator of the conspiracy behind the scenes. Moreover, the relationship between Luo Zongliang and Lin Ziyu is not simple. Could it be that Lin Ziyu is really a senior commercial spy sent by Luo Zongliang to Manlin Public Relations Company? Fan Shuchen and Lin Ziyu were both caught in a love-hate relationship, but after the truth came out, with the joint efforts of the two, they not only cleverly punished Luo Zongliang, but their love finally blossomed.
