Sadi Gali Translation - Tanu Weds Manu

Sadi Gali (Our Street) is a song from the movie, Tanu Weds Manu. I never watched the movie. (And I'm too lazy to check the plot on Wiki). All I know is that it's about this guy who is arranged for a marriage with a girl who drinks and smokes. And nobody actually knows that except for her, I think, best friend or sister and some others. They start to get to know about each other. And I don't think I'm right, but I think that's it.

And I couldn't translate this whole song without some help. It was hard, especially since I'm forgetting my language a bit, now.
