High school student Zhu Xiaoli fell in love with her classmate Cheng Xiyuan at first sight, but her introversion and low self-esteem made her shy away from this inner throbbing, so she kept silently paying attention to Cheng Xiyuan. At this time, Cheng Xiyuan had been waiting for her silently before Zhu Xiaoli had a crush on her, but Xiaoli didn't notice it at all, until a seemingly inevitable but accidental opportunity allowed them to truly intersect. It is precisely because of this opportunity that Xiaoli's character has changed, allowing her to struggle silently on her emotional journey.
