Her best friend stole the senior she fell in love with as soon as she entered college?
The estrangement between the sisters was not resolved until after graduating from college. It was not until after graduation that she went to Hong Kong to further her studies while she stayed in the mainland to work.
It turned out that she was still thinking of her...
"I can't solve my own emotional problems, so how can I help my junior sister solve her emotional problems?"
"You can't solve your emotional problems precisely because you have too many schoolmates!"
It turned out to be this stinky man jumping back and forth between them! She saw through this man and left without any regrets.
