If you are in a mood to watch a complete love story (without any additional sub stories) and if you like haters-turned-lovers kinda story,then you have got the right one here.It starts as a love quadrangle but goes in the expected direction as it proceeds. I totally loved this drama. Some warnings: ->Absolutely no romantic scenes,still very cute to watch. ->Draaaagging after half of the episodes. (but by this time you would have fallen in love with this story,so you will enjoy watching no matter what) ->Other than the characters,I felt like music was the one that gave the feel of the story.As I said,it was dragging,so music had to fill the part. One thing I like about this is, usually in all the dramas, although the main roles know how they feel about the other main role, they will not communicate their feelings properly (mainly to drag the drama).Here,the problem is a confused state of mind between 2 of the 4 roles.They are not sure what exactly they want, which I find very realistic. Casts are perfect,though I felt rain was overacting in many places. may be his character was meant to be that way. I haven't seen another korean drama with great music like this yet. Can rewatch it after leaving a long gap.
