Zheng Lun knew that Zhao Anan had been diagnosed with cancer, but it was Zheng Jing who had told her about it.
So Zhao Anan didn't know that Zheng Lun had already known about her condition.
Zhao Anan left the Zheng family in a hurry and went to the criminal Police unit to find Zheng Jing, regardless of PEI Xinhua's persuasion.
However, Zheng Jing was not in the police unit. He was still at the scene of the murder and had not come back.
Zhao Anan wanted to go to the scene of the murder to find the person, but the criminal Police refused to tell her where the scene was, because this kind of criminal case had to be kept strictly confidential. They didn't know Zhao Anan's identity and couldn't tell her the location.
Zhao Anan had been waiting for him in the criminal Police unit. She did not see Zheng Jing until five in the afternoon.
