This is so good! Personally one of the best drama of all times. The cast portrayed the characters well, the edit and the cinematography was well done. I especially liked Kwak dong yeon's scene. Where you can see the point of view of someone who suffers from manic episodes. All in all, it's not your typical drama where they always end up together and have a special connection that makes their relationship build quickly (childhood sweetheart etc). In this case, the male lead didn't had find memories of her. Hopefully the ending doesn't disappoint! I really love the stories so far, and the deep message behind it. Fighting!
