Jenny's husband David once again entered the system through brain signal simulation and took control of Doug. Just as David was about to kill Jenny, he was killed by the detective who came. Because David's brain signal in the real world is left in Doug's body to die, Doug's body is already full of David's brain signal, and the extra Doug's brain signal can only be transmitted back to David's body in the real world in 2024. In this way, Doug jumped into David's body from a virtual world and entered the real world in 2024. The evil David died in the computer system forever, and Doug started his life in the real world with a new identity (David). This is a happy ending. My own opinion, I hope it will help you.
