The thing about Korean dramas is, sometimes there's not enough story to fill the number of scheduled episodes, and other times there's too much story and not enough episodes to cover all the stories. Thank goodness for this show, which shows that when a story and its characters are plotted properly, a simple drama can start off on the right foot and be wrapped up neatly at the end of it. This is not the first drama I have seen Kim Seul Gi and Doojoon in. They are both actors and seem to be good at getting the right chemistry with their fellow actors. They are really cute together in this show. The concept of this drama is not 100% unique. There are a few drama tropes like time travel, cross-dressing, and high school pressures. But we all know that when the tropes are used in the right way in a drama, it can still be a very enjoyable watch. Although the female lead character is a high school student, the themes of wanting to escape a miserable reality and realising your true potential are relatable on all levels. I think this show will be a great watch and source of respite for hardened Korean drama viewers who are tired of watching the same tropes being used in the same way again in drama after drama, or of episode extensions with too much filler and no storyline progress. A short but refreshing watch!
