My only request to creatives is tht give characters some space to expand and grow for good but tht does not mean tht these characters have to be ruined. In my opinion mayank's character was one of the best sketched character of all times. he was this ideal frd, son, student....yet realistic and cud have been an ideal boyfriend. changes do come after someone gets into a r'ship but the changes tht have been shown are written wid nupur's style and choices in mind not mayank's thinking and way of life. His changes r directed to please nupur all the time. Mayank was a kind of character wid so much confidence, attitude and substance that even if he has to please someone he wud do it his way. He is shown to be intelligent enough to do things in his style still leaving a lasting impression. He being the mature one should be able to balance out their r'ship incorporating both his simplicity and nupur's funny filmy ways in moderation.
I guess i've rambled on too much and sorry tht this post has become so long specially this being my first one. But wud love to read your views on this topic. I'm sorry if this post offends anyone in anyway. I respect everyones POV and this is just my opinion.
