Yinyin, She's Your Sister?

The news that this monthly examination's top student came from Class Twenty spread throughout the entire Year Three cohort like wildfire.

Even Shen Huan became famous in her year. Gu Mang also shocked the entire Year Three cohort by coming in last place. Upon hearing this news, Principal Fu questioned his life. Had Director-General Lu confused her with someone else? Meng Jinyang was the top student of the year while Gu Mang was the last student.

How could she score a zero even in English???

...

At a six-seater table in the school cafeteria.

Fatty Ling watched Meng Jinyang quietly. Dumbstruck, he said, "I never imagined that I, Ling Qian, would know an academic genius in my life. Meng Jinyang, you're too pro. It's one thing to get first place, but to be able to improve Shen Huan's rank too—you're really too pro!"

Lu Yang and Chu Yao were full of admiration for Meng Jinyang. How did such an academic genius come to Class Twenty?
