Why did the director of the hotel, Wang Bai, retaliate?

Because A Cheng Yuan and Bai Meiwa used to be lovers, and Bai Meiwa loved A Cheng Yuan, but Li Zhongjiu violated her and got pregnant. She went into hiding and secretly gave birth to a child. A Cheng misunderstood Bai Meiwa's betrayal because of a single transaction. He didn't listen to Bai Meiwa's explanation, so he called the police and handed her over to the police. From then on, Bai Meiheng hated Cheng Yuan and Li Zhongjiu who defiled himself. In order to get revenge, I changed my name to Bai Meiren, lurked in CL Hotel and turned into a hotel training manager, with the ultimate goal of capturing CL Hotel.
