1.) Why I watched this - Honestly I didn't watch this for the longest time the synopsis sounded really stupid and sounded just like a romance between workers , however about a year ago I was looking for something to watch and I finally watched this , BEST DECISION I EVER MADE 2.) Why you should watch it - This has such an amazing story line that the synopsis does not do justice, the acting was amazing and there's a strong female lead ( even though shes stupid at times i"ll let it off this time) also there are so many great and important details that the first time around i didn't see ( all in all i have watched it 6 times and find something new every time) They also mix SOME humor in to it, there's romance and there's just so much suspense, you will be on the edge of your seat i promise you 3.) The music - This soundtrack couldn't get any better i promise after your done watching it you'll be going - Oh its alrightt~~~~~ so so so many great songs i mean there's jonghyun and girls day and just so many many many great songs
