Why vansh couldn't read her said this already I guess its in last page. It's his attitude which is to be blamed. Don't want to go round & round. Let's end it here. Hope we get the chance to talk about this another day.
Then I would disagree.
Vansh is an intelligent man...Has been living with her in the same room for 6 months...observing her very closely. Why could he not do the same? It should have been easiest for him to control her.
One of the things where I see Kabir's intelligence is that he maintained his positive facade till Riddhima herself found out about his plan. Despite her taunts and accusations, he kept on pretending to be a well-wisher...not letting his mask down for once.
Had Riddhima not found out about the school bag, then chances are that after months, she might have even forgiven him.
