The medical team didn't find any kind of drug in the postmortem report. The whole scenario was looked like suicide so the police had announced that Xia Xiulan had committed suicide.
However, Liu Yang knew that it wasn't suicide. Gu Minlan killed Xia Xiulan, Liu Yang had proof but she didn't trust anyone, not even the police. Therefore, she had waited for Yue Wanwan's return.
Meanwhile, Mo Qiwn didn't show up anywhere near Xia Xiulan, even not at Xia Xiulan's funeral.
Yue Wanwan came back and she and Liu Yang went to the head of police officers as Xia Xiulan's death case was very sensitive for many fans and Yue Wanwan believed that high-level officers wouldn't be like lower-level officers who would be corrupt for any rich people.
However, she was wrong, that head of police officers handed over the evidence to Mo Qiwn instead of arresting Gu Minlan and soon after, Gu Minlan also got to know about the evidence.
