Om was wrong in bringing her there and misunderstanding Shivaay. While he could not tolerate the lies of Riddhima, he is ready to forgive his bua. Blood is thicker?
And how he will tolerate the chor and cheat Ishaana? Just because she found it easy to do so than work hard, her acts are not forgivable. this trapping a rich man is also demeaning of a lead. Her father looks like a sadakchap.
Roop and Ishaana are two sides of the same coin. Ishaana is a bit better.
