Just..such an awesome story. The usual relationship misconceptions that are so present in the dramas nowadays aren't in this one, and its a relief. The story is really well written and well played out. When its sad and you feel sad, its happy and giddy and you feel the same way. Not like rooftop prince at all except the time travelling, the ending is satisfying and the whole show is just great. If I could give the story a score above 10 I would.
