(Background below)
Z University - the best university in urban area A
G University - the second best university in urban area A
R University - the worst university in urban area A
Lu Jingming (male) has been ranked first in Z University for five consecutive years. His reputation has spread to R University. Jiang Chuyao, Lu Jingming's dog-killing enemy (it was a misunderstanding), heard about it. Jiang Chuyao couldn't hold it in, so he worked hard and was admitted to G University. And then - yes, that's sweet.
