Mu Mu knew that Chen Qingqing and Chen Feng had adopted Zhong Bingyuan, but he did not know the details.
Zhong Bingyuan said, "I don't remember my past, but I still remember how to read. I think I must have gone to school in the past. Now I'm getting ready to go back to school!"
Mu Mu was extremely intelligent and was already in university although he was so young. At the time, the university students were comparatively older, and some students were quite old.
So Mu Mu's social circle included very few close friends. He had even fewer friends among his peers.
So, in just a while, he became good friends with Zhong Bingyuan.
