"Just say that you love me once, and then you will come to know why I don't have any other topic to discuss besides love."
Riddhima cleared this in simple words to Vansh that she never loved him nor ever felt love for him. They justs stayed together as a couple due to the circomstances brought to them.
But even apart from circumstances, Riddhima has been saying that there are no chances of it to ever happen, "Real love but not for Vansh."
Vansh died after her and for her, it was not a small thing. Why isn't she always valuing his love by accepting him?
It is due to the fact she thinks, "I can not absolutely love such a murderer."
Vansh murdered, "He did not homicide your love. Was it all a game performed by you to make him fall in love with you?"
"Which love? I was never interested." She requested as if she was sincerely unaware of it.
Then he replied, "Whom you are watching to be standing with you. That's why you were here, right?"
