I think meenu's fiance will dump her and Faazi of course won't be able to marry Hania then. They will then have to marry each other and the characters will develop into a toned down and mature version from there on. The ost shows them in Faazi's bedroom aa well as him holding her hand in the car. Meenu also seems to be less childish in that clip.
Other than this I can't see how they will introduce a love story between the two. It cannot happen organically before marriage since Meenu keeps calling him bhaiyya and Faazi is very stubborn with his ideal type of wife.
Good predictions. I like these types of lovestories where the couple don't think romanticly about each other.😃 It is a challenge for the writer to convince audience .😉 For this we get lots of meaningfull scenes between leads.😳
