The Story with Mr. Lu

The Mr. Lu I met when I was ten years old is different from the Mr. Lu I met when I was sixteen. I have known Mr. Lu since I was a child and know about Mr. Lu. A few years later, when I saw Mr. Lu again, it was different. This time, I knew nothing about Mr. Lu. We are friends with Mr. Lu, but not lovers. The story with Mr. Lu is very simple.
