If you put yourself in the place of Rummi, you will end up being totally messed up in the end. It's too difficult to decide whom to choose , when you love both of them. So just go and enjoy the mixed feelings of love with the songs placed beautifully at the situations... Remember it's a love story so if you expect THE ANURAG KASHYAP EFFECT in everything then you won't find anything satisfying, in that case may be you should just go and watch Gangs of Vasseypur again.
Also, don't forget to get out of the character when the movie ends ;)
