Su Yu is a bit of a scatterbrain. Her days consist of studying and going home, following the same two-point route. One day, after her classmates play a prank on her, she gets on the bad side of a student with a terrible reputation:
Lu Jing. To her surprise, he remembers her name and keeps pestering her from then on.
Lu Jing never expected that one chance encounter with Su Yu would make him fall for her completely. When he teases her, she makes the face of a little kitten, and he can't help falling for her.
So he sets out to win her over.
