I didn't expect the roller coaster ride that this drama ended up being. I am still on a high from marathoning this drama in three days. The storyline while simple takes so many turns and twists that it keeps you guessing the whole way through. What would you do if you had a chance to change the past? that is pretty much the plot of the drama but so much more. This drama will make you smile and cry and laugh. Jin Wook is truly amazing in this role, you love him from when his first character appears. This drama is a must watch...
