Who was the murderer at the end of the second season of The Lights On?

The murderer who killed Su Qingyi at the end of the second season of Deng Huachu has not yet surfaced. Judging from the male and female voices heard on Jiang Han's wrong tape recorder, Hanzi and Ada are the most suspected. In addition, Ada finally hit someone with his car, and the murderer has been basically locked, so there is no suspense. Its motive is nothing more than Hanzi's accidental killing of Sue to protect Luo.

The Story Background of Deng Huachu's Merchants

1987? Year? 7? Month? 14? Three students came to Guang Guang with their birthday wishes. Aileen hid when she saw them, and Qingyi greeted them. Lily is sour, and Aileen comes to exchange with Qingyi. The students found out that she was a journalism major, so they teased her, helped Aileen quit drinking and sang Kara with Qing. Ok.

After work, Qingyi found Yu En drunk at the door. Yu En said that she likes Qingyi, and Qingyi also said that she likes him. 1988? Year? 10? Month? 6? The police suspected that the murderer dragged the body for a distance and then used it on his back. Three months ago, Aileen dragged Eun home drunk. Yu En thought she was Qingyi, and suddenly choked up and said that she would kill her. Aileen pushed her out of bed.

Nong Yu came to Qingyi and said that last week, the water and electricity master came to repair the air-conditioning fashion display. Qingyi was very nervous, but Nong Yu only found Qingyi smoking and asked her to put down Yu En and come to school to find Wei Zi. When Wei Zi came home, he told his mother that his father had visited him three times, but he asked his father not to see him again. Because he didn't want to make his mother angry, Nong Yu suddenly got a call from the police station, saying that Liu Shaoqi had beaten himself after drinking, but he didn't have the money to pay the fine.
