It is true story of the author. Often we come across some real stories far better than the reel stories, and this story is one of them. I really feel that the female protagonist is some kind of angel whose main intention is to make us realise essence of true love through eyes of the author.
Story is realistic and author never made an attempt to erase the originality. People always hate things which make them cry at the end. Yes this story has genuine reasons to cry at the end. I really hate such stories which end up like this.
