Riddhima should start treating him as a stranger and remove all those marital symbols. Ignore him and give importance to people who respects her. Whenever he tries to show his rights on her, bluntly reject him by reminding him that she is a stranger to him and he shouldn’t exploit a girl. For my evil heart’s satisfaction bring a sane guy to woo her even if they don’t end together but just to see Vansh burning in jealousy and turning into ash.
