Yan Yu found it very strange, because with Zhang Huaide's cautious and old-fashioned personality, he should know that high school romances seldom last. How could he do something so futile and bound to fail?
After careful inquiry, it turned out that his girlfriend was too impressive. To prove that she could attend the same university as him and that they wouldn't break up after graduating high school, she spent an entire semester forcibly raising her ranking from over 300th in the school to the top 10, becoming "a woman worthy of Zhang Huaide."
Doing the math, she was still underage at the time! Using the excuse of love to deceive an underage girl into focusing on her academics, Zhang Huaide surely is something else.
