This book uses a pair of sisters with very different personalities and huge age differences as the protagonists to tell a modern urban love story that breaks the rules. The "leftover" sister who is surrounded by negative rumors has a wonderful career and is full of style, but suddenly confesses her love to the handsome boy next door; the rebellious sister who is addicted to the second dimension has a quirky personality but is a complete scumbag. She failed the CET-4 test many times, but fell in love with the high-tech elite uncle who lives alone with his son. And when the elder sister's career encounters the biggest crisis, when the younger sister's bad academic nature makes it difficult for her to get along with the academic uncle, how can she break the situation in her life? Fortunately, there is love and you are not alone.
