every tom dick and harry in the show says karan and preeta love eachother but they never realize it themselves 🤣🤣 most of the audience dont see any love between them either. like you said there are no signs of love. they dont care, trust or respect eacother and they dont stand up for eachother esp karan. and when preeta is shown to do it, her pativrata aspect is highlighted i.e. she is shown to do it for the sake of her marriage.
looks like its not love but the illusion of love which writer tried to create 😆
They do care for each other (karan on-off mostly) but other than that, ZILCH! 😆
