I thought I had seen all of the best love stories, but I hadn't seen this one yet! Kang Ji Hwan and Kim Ha Nuel were amazingly, talented actors to have portrayed the characters in this bittersweet romance. The supporting characters were written to be rather cold, cruel, and lacking in understanding, though it wasn't their fault that they were that way. All of the actors did well, especially the 3 lifetime friends bromance! If you aren't one who likes a very sad drama with periods of laughter and love plus many tissues used, then this drama isn't for you. IF you want to see how characters struggle with the problems life deals them and you don't mind heartbreak tears, then you will enjoy this!!! It's a very slow moving glimpse into the lives of these special friends... It gave enough time to truly understand the characters. The music seemed at first out of place (all American songs mostly older than the time period of the drama); but as the episodes went by playing the songs as memories of places and times, I began to truly enjoy it. There was also some beautiful Korean music that wasn't subbed, but seemed to go along with the feel of the drama. The story line was a bit repetitive, but not so much that it conflicted with the total character development. Actually, I loved ALL of it and rated it 10/10. Don't know why others rated it lower...
