This book is also ABO, but it is modern. The story is that Xia Yuhang from the biology department annoyed Yin Kong from the mathematics department at the beginning, and always thought that Yin Kong was an A, but he was obviously an O that looked like an A. But Yin Kong didn't like to talk and Xia Yuhang didn't know. Xia Yuhang later found out whether his best friend was an O or a genius in the biology department... But because of this, the two had a big quarrel, until the day of the sports meeting, Yin Kong ran around like he lost control...
Intention: It was also because of a dream...
