Jing is a high school girl who endures harsh ridicule from her classmates after her confession of love to a boy named Tianyan is rejected. Humiliated and labeled as ugly, she vows to transform herself by losing weight and enacting a plan for revenge: she will make Tianyan fall in love with her, only to turn the tables on him. As she pursues this goal, however, a series of unexpected events causes her to reconsider her motivations. The story unfolds in a school setting, blending comedy and drama as Jing navigates her shifting feelings and the consequences of her scheme. Over the course of the narrative, Jing's initial desire for vengeance gradually gives way to second thoughts, leading her to question what she truly wants from the relationship and from herself. Notable narrative arcs center on Jing's physical transformation, her evolving emotional conflict, and the tension between her original revenge plot and her growing genuine feelings. The manga concludes without resolving whether Jing ultimately follows through on her plan or chooses a different path.
