Cheng Qingchong left the room only after her mother had retired for the night. Qin Yinan was no longer in the living room; the lights were off, but the television was on with its volume tuned down to its lowest, casting the hall in flickering lights.
Since they were playing the part of a married couple, naturally, they had to sleep in the same room. Furthermore, Qin Yinan's apartment only had three rooms and one living room. Two of the rooms were designed as bedrooms while the remaining one had been repurposed into a study. Mrs. Cheng had used one of the two bedrooms, so only the main bedroom remained.
The light in the study was off, so Cheng Qingchong knew that Qin Yinan was in the main bedroom. She struggled for a long time at the door before pushing the door lightly open and walking in.
