How many endings does gossip detective have?

The ending feeling of gossip detective is that the author is paving the way for the next work, because many holes dug by the author are not filled in at the end.

He was killed because three years ago, four people, He, crashed into a lover's car (gay) on the night of Qi Hongmei's singing competition and wanted to take the blame (because she didn't have a driver's license, but she could drive). Later, because she found out that Shao Qing's lover was taking drugs, she blamed herself for the death, but Shao Qing thought that Xiao Lei didn't call 120 for help in time.

Extended data:

After he was killed, he disguised himself as a murderer and lived incognito in other places. Three years ago, the deceased was Qi Hongmei's twin sister, a drug dealer in Guangzhou.

Qi Hongmei wanted to cheer up her sister, but when she was emotional, she took medicine and jumped off the building.
