Although this drama has only two episodes, it manages to present the story beautifully. Also, even though it is dealing with time skipping and going back in the past to change the future, they did a great job with that difficult theme. The performances were great as well, and the sweet, emotional story helped a lot. The love story as well was fresh and warm and it dealed with loss, depression and bullying, themes that are difficult to deel properly as well. The ending, finally, was satisfying and I couldn't have imagined a better ending for this story. So, all in all, 8 out of 10.
