This is one of the best dramas (if not the best) I have ever seen. To begin with, I thought the story was fun and refreshing. We have the typical love triangle, but it doesn't feel too long as it sometimes does in other dramas. The characters solve their issues pretty fast and in a somehow realistic way (taking into account that the circumstances of the show are not supposed to be realistic at all).  The actors did a great job too. I immediately fell in love with most of the characters, especially the two leads. Their chemistry was amazing, and their screen time together was glorious!
