Tengoku to Jigoku: Psychona Futari (2021)

He Fei's wife, Li Mu Zi, disappeared mysteriously during their wedding anniversary trip. While he was searching for Mu Zi, she appeared again out of nowhere, but he insists that the strange woman in front of him is not his wife. Lawyer Chen Mai gets involved in this bizarre case, and more mysteries slowly emerge.

In both dramas, there is a body swap between a policewoman and a criminal. I would say Room No.9 is darker than Tengoku to Jigoku: Psychona Futari, which is more humorous at times, but still pretty intense and dark.
