We all have regrets in our life. Some big and some small. And only one thing comes out of it, Only If. Only If, I could go back in the past and change that so that I won't regret it in the future. Only If, it was possible to do that. Let's see what happened with a couple, who was also each other best friends, that they also think about this 'Only If' This is a short story. Give this story a try, guys. I promise you won't regret it. The plot was given to me by my friend @ankitaghosh205. And I am going to write this story.
