Xie Ye didn't know how he got back to meet Xu Lun. But one can see through the way he walks while avoiding most adults on the way, that something was wrong with him. He bumped on the grumpy looking adult whom Gui Lan met before. This man was standing outside the office where he left Xu Lun. It is the secret agent whose name is called Ke Lou. Obviously this adult recognizes him.
Ke Lou smirked at him, "Kid, finally awake huh?"
