Versatility of the actors

I love this kdrama. I've already watched it four times. I love all the characters, both the good ones and the bad ones. All the actors are amazing. The story and the music are spectacular. I recommend this kdrama to everyone who loves thriller, dark comedy and romance.

It's favourite kdrama and Song Joong Ki is my favourite actor. As an Italian person I give 7.5/10 for his Italian, I almost understood everything he said. There is only one thing I would have loved to see more about his character: his past in Italy.
