This drama is one of the best series I have ever watched...regardless if it's Korean or not. Where do I start? The story itself is heartbreaking but in the way that sometimes real life is. The nuance performance by IU and Lee Sun-gyun deserve enough recognition to last a lifetime. I also especially enjoyed the storylines of the 3 brothers that fight and bicker but most importantly, love each other so much. I don't want to say too much but I wanted to write this review and encourage EVERYONE to watch this treasure of a story. You will thank me later!
