If I had to describe this drama in one word, 'Beautiful' would be it. I wasn't anticipating it and started it because the title drew me in and I'm so damned glad that I did. This is one of the best written drama stories of this year and I can't not write a review for such a gem. When I first heard the synopsis, I was very skeptical about how the drama could tackle the serious aspect of the plot, with it being promoted partly as a comedy. I didn't want the depth of the main leads' situation to be overshadowed. And as I write this review, having finished the final episode, I'm left with a feeling of bittersweet satisfaction. I love this drama for being so different and tackling such an ambiguous issue. I love it for showing such complex characters, for having them portray so many facets of a person going through such an issue. I've had personal experience with cheating in my own family and I learnt so much from that time in my life and understood this vast greyness behind the black and white way cheating is viewed as in our society. I LOVE this drama for breaking from those stereotypes and trying to show different kinds of ways it happens and I hope for all those people who view cheating as 'wrong', through this drama, they can understand to a certain extent that sometimes, there is no right or wrong, that there is so much more going on beneath the surface that leads a person to do something like that. Acting: The entire cast has played their role so well! This is evident in the amazing chemistry between all of them. Especially loved the two main leads. Not for a second did I ever think of them as Song Ji Hyo or Lee Sun Gyun. That's how immersed in this drama their acting made me. Music: Great songs overall and 2 I instantly fell in love with are- Mistake by Park Won & That Kind of Night by Urban Zakapa. This was one of the best drama experiences of this year and I hope many many more people can enjoy it too. For all those people who're unsure if they should start this drama, please definitely give it a try. Whatever your views on cheating, I'm sure you'll discover something new about yourself and about the complexities of human relationships after watching this.
