I haven't enjoyed a drama like this since SKY Castle. Very well written and acted, this drama just carries you away with it and makes you feel like a voyeur in the characters' private lives. You grow to both care and abhor them because they are imperfect. You wonder why they do the things they do instead of letting go and moving on. If anything, this is a lesson in human behavior and the consequences of our choices.

A friendship between two women is destroyed when one makes a bad decision, leaving the other to pick up the pieces and plot her revenge. This drama was a well-written race to an explosive end. The train is out of control and will eventually crash, leaving the lives of the those around them in shattered pieces.

I have to commend the performances of all the actors, particularly Shin Hyun Bin who is the polar opposite of the character she played in Hospital Playlist. It was refreshing to see her explore her creepy, darker side. Kudos as well, to Go Hyun Jung whom I fondly remember in her role as Park Wan in Dear My Friends. Both women carry this drama beautifully and kept me glued to my seat. Notable mentions also to Kim Bo Yun as the meddling mother-in-law and Choi Won Young as the wronged husband.

Unfortunately, the last two episodes tried to wrap up the drama in a very unrealistic way. I can overlook how unwanted people are constantly breaching this upscale neighborhood to cause all kinds of mischief, but the ending was just too implausible. I wish the writer had been able to put as much effort into the last two episodes as she did in the first 14. She wanted to give it the ending audiences might have wished for given the circumstances, but I found this ending a little hard to swallow based on the vindictive personalities of all those involved.

OST is beautiful and perfectly suited to the drama. I would definitely watch this again.
