Several more minutes passed, yet Han Shuang was nowhere to be seen. Unable to contain his anxiety, Chen Kai finally dials Han Shuang's number.
He waited for quite a long time until, right before the system was about to say "The subscriber you are calling is busy, please try again later," he finally heard Han Shuang's voice.
"What is it? I'm looking for some documents here, why did you call?"
Chen Kai sighed in resignation, "Do you realize how long you've been upstairs for? You haven't come back down, I was worried something might have happened to you. I could go up and help you look."
Once his words fell, he immediately hung up the phone and opened the car door. Standing at the car's entrance, Chen Kai took a long breath, hoping fervently for nothing unexpected to occur. The memory of the previous incident was still enough to bring him too much embarrassment.
