Chu Xi didn't work on weekends, but insisted on following him; it was like this every week. After a while, he could not be bothered to mind her. If she wanted to follow, he let her be.

About ten minutes later, she took out the surveillance footage.
Mo Shiqian walked over with Chi Huan, sat down on the long sofa, then brought his laptop over and opened the playback of the surveillance.
