Ye Chuqi is recognized as a "confused student" in Class 2 of the second grade of junior high school. He fishes in class and relies on copying assignments. His biggest wish is to pass mathematics. The biggest "accident" was that he ran into the arms of transfer student Huang Liang at the corner of the library - not only spilled warm water on him, but also exposed his wrong answer book full of graffiti.
But who would have thought that this taciturn transfer student with an aura of academic excellence would actually become her classmate. What caught her even more off guard was that Huang Liang not only didn't care about the embarrassing situation, but also took the initiative to pick up her wrong question book and started the "Reformation Plan for Academic Scumbags":
It was the analysis of wrong questions that was secretly stuffed into her drawer during class, with neat handwriting and cute auxiliary lines; it was the figure who patiently explained in the library, turning complex formulas into "orange sweetness"; it was the gentleness that blocked her punishment at the sports meeting, and the closeness of sharing an umbrella on a rainy day...
The poor student girl's wrong answer book is gradually filled with exciting formulas; a reckless and cute little sun also breaks into the world of the aloof academic master. It turns out that the sweetest encounter in youth was when I ran into your arms, and you just caught all my confusion and uneasiness.
This is a story about the two-way journey between a top student and a bad student.
