This is such a cute and heartwarming movie. I really loved watching it. I already watch it twice, once alone and then with my friend. Song Ki is such a great actor and I really felt this strong relation between the two main actors. It was also my first korean movie I watched and I totally didn't regret it. So guys if you want to see what happens when a girl and boy from different "worlds" meet, then you really have to watch this drama. You won't regret it !
