Eun Dan-oh (Kim Hye-yon) attends a prestigious school but one day she discovers her life is not what it seems as she is in fact a supporting character in a web comic. Once she comes to terms with it she decides to change her life and become the main character of the story. It is a romantic drama and Rowoon plays Ha-ru a fellow pupil and together they make a cute and believable couple. It is a clever plot where she has to change the authors plans for her character but it does not get too complicated. It is actually based on a webtoon, which I find amusing and the acting of the whole cast is good, so well worth a watch.
