After Song Qingchun filled the tub with warm water, she shed her clothes, and as she placed one foot into the tub, she could hear the sound of a car coming from outside.
After a short hesitation, she pulled her leg out of the tub, wrapped herself with a towel, walked to the balcony, and looked down.
As she'd guessed, Su Zhinian was home.
The car deposited him by the gate. It did not come into the compound. When he got out of the car, he leaned into the front window, probably to thank the driver. After less than a minute, Su Zhinian turned and walked into the compound.
Song Qingchun waited until Su Zhinian had reached the front door and was keying in the password before she realized what she was doing and rushed back into the bathroom.
The bathroom was quiet because Song Qingchun did not turn on the tap. Song Qingchun, who was soaking in the bath, could hear Su Zhinian change into the house slippers and walk into the study.
