One way it's right is because in Bombay any person can be anonymous, swept away by the tides of thousands. Different castes and religions get blended together. A person can disappear if they want to, reappear with another name.
It can be wrong because in Bombay there is no privacy. Lovers have to go to Bandra Bandstand, and sit along the rocks on the beach and kiss. Prudish mammis tap their canes on the lovers backs, but there's nowhere else for them to go.
Perhaps love is right and wrong for every city, but in Bombay it feels more so.
