I've watched this drama two years ago, and I still remember how much I loved Kang Ha Neul in his role, he was the first favorite actor that I've ever liked!
Abut this drama I really liked the story in itself, I loved the ambulance stories and how they met and leave and met again during their life.
I left the last episode from watching because the ending was predictable but still enjoyed it.
The story is also more mature than the other rom-com drama, don't expect cheesy scenes but something that tends to get on the really dark side in many scenes!
