Im a fan of both leads so this was a must see for me... Not only did I love the main characters (cute chemistry) but I loved the supporting characters too (yay Park Ki Woong). There really wasn't much to the story though. You just see how they meet and then how they spend their days counting down to their deaths. Its twisted but somehow the writers made their relationship and their activities seem so normal. It really is a very easy breezy watch. I feel like it was a bit too long that I started to get restless towards the end. I loved the ending, it was realistic but hopeful at the same time.
