In the summer after the college entrance examination, Lu Zhixia rescued a girl who couldn't reach the book in a second-hand bookstore.
She called him "little friend" and he called her "Shen Nian".
When school started to select courses, he opened the door and walked in. Standing on the podium was the confused sister who had picked up the wrong picture album in the bookstore.
"I'm a guest lecturer, you can call me Teacher Shen." The whole class was wondering if she had a boyfriend.
Only Lu Zhixia knew that the note she sent him on her phone was: kid.
