What a great great show. Now I know what the hype was all about. Watched a show like this after a really long time. It had all kinds of emotions that are required to make a good show. It really is rare for me to write a review for a show but for this show I couldn't stop myself from writing one. I cried, laughed, felt the love, friendship and every emotion that one can feel. Its just so heartwarming and warm loved it so much. It is also so thought provoking that everything happens for a reason and we should just let things be and enjoy the moment, twinkle while we can everything else will come in place too, like how Eun gyeol wanted so bad to save ha yi chan from the accident but it had to happened and it happened but they also showed that he was happily living with it and didn't stop twinkling. You should definitely watch it its just so good to be described in words.
