If I could change the past

I was happy. I was so so happy and then suddenly my world shattered into pieces.
Everything is a mess now. A big and complete mess. I want everything back, my happiness back.
And I'm gonna bring it back.
But what about the future??

Sohan, is your typical kind of a guy. Didn't like drama and was always away from trouble. in his usual happy and simple life he finally finds a beautiful reason which makes his life more intresting and exciting in the presence of a girl, soha.
But does fate wants them to be together?? and if not, can we actually change our fate??
