The sun was setting and dusk was approaching. Wu Yi returned home from get off work and rested for a while. When he didn't see his girlfriend Ruolan coming home from get off work, he got up and went into the kitchen to cook. He checked the time again and again, calling her several times but no one answered, and he couldn't help but put an anxious look on his face. He thought that, logically speaking, Ruolan should have gotten off work long ago and returned home long ago, but what happened today? Haven't you come home yet?
Just as I was thinking of this, suddenly, there were rapid knocks on the door. He immediately became happy and walked out to open the door.
As expected, Ruolan is back...
