Marriage has made me learn a lot of things. When as a bachelor we see people like kabir v instantly hate them,but when they become husbands wives learn to tolerate them. Most men have thinking like kabir,its not his fault entirely it's his upbringing that makes them as they are. Zara belongs to a liberative family hence she is what she is but kabir has been exposed to such ideas from childhood so he feels his thinking is correct.
Now coming to characters as I said Zara openly defied kabir before marriage but now as a wife she has limits. And it's normal to change yourself after marriage. A wife needs to compromise otherwise there will be oly 1% of marriage surviving in the world. Having said that there must be limit to compromise also u shouldn't compromise to a level where u lose ur self respect. Zara is making her marriage work which is normal for every women .her compromised wouldn't go waste one day her husband would realise her worth he would love and respect her for entire life.
Kabir : kabir is a man of strict principles. He has spent his entire life on learning and respecting them. Asking him to change in Day or in a month is too much. He needs time to understand and respect Zara's thinking. He is a good husband but for him an ideal wife is someone who cooks clean and maintain his house like how he and seen his mother and bhabhi do. To accept and support Zara he woould need a little more time I guess. Or maybe he would realise his flaws oly after Zara leaves him. Therefore this marriage either way will leave back a transformed kabir. Now what price will this transformation take will be interesting to watch
