One day, He Yinling mentioned in a conversation with her class teacher that she "wanted to have one more class representative in mathematics."
The class teacher approached Ye Er and asked him to be another class representative.
He agreed.
Later, one night during military training, He Yin Ling was watching people downstairs playing badminton in the corridor. When taking a picture with her camera, she "accidentally" zoomed in on Ye Er.
At this point it was out of control.
Mathematics is the language of the universe, and you are my optimal solution.
