The characters, kunal and nandini are the most disgusting couple ever. The makers through the couple's dialogue try to show their "love" is pure, yet their actions prove otherwise. Kunal is a character who has no justifications for cheating on his perfect and loving wife besides the fact she doesn't dress up 24/7 like nandini, as his wife actually has a career, so kunal's so-called pure love for nandini looks more like lust as she serves him food and dresses up to impress him.
On the other hand you have the most disgraceful character called nandini. She has no job, no talents, no self-respect, only had desire to have a man who will treat her like a bloody princess, for which she makes sure she is dressed up all the time and her cooking skills are on point, then when her best friend warns her that her fiance is a pervert, she ignores her best friend and accuses her of lying, you know, because nandini's hormones are more important than friendship, which she then proves again by stealing the same friend's husband even after her friend saved her from the same man her friend warned her against marrying, yet this nandini has the nerve to act all innocent as if she's done no wrong. She refused to believe her friend when her friend says her fiance attempted to rape her, then when her friend saves and supports her, she steals the friends husband to replace her previous husband. Even a prostitute would be sickened by her for stealing and sleeping with her saviour friend's husband.
After all this the makers keep trying to prove there was nothing wrong with what kunal-nandini did and try and justify their affair by saying affairs are common. Just because something is common, doesn't mean it's right. WHAT THE HELL!
