this is by far best performance of lee jong suk. I am a huge fan of lee jong suk and i believe this is his best performance so far. this serial has best emotions and acting skills. i really loved everything including music, story and lee song juk. Although i do not understand korean very well and mostly understand through subtitles, but i love this serial.it is such a cute love story and everyone is so well connected. i love lee jong suk acting and his chemistry with actress. i have watched it twice and i am still wanting to see it again
