Its a serial, there is no logic.
Its a serial where khushi thinks putting a lock n key in dargah, or flying a kabootar, makes wishes come true.
This is a serial where the lead believes a dupatta thrown by a man landing on a woman's head means devi maiyya will get 'em married.
This is a serial where the leads ALWAYS end up in the same place at the same time
There is no right n wrong here.
Just enjoy the show n if u. Guys didnt question the above istuff, don't question the morality aspects.
Also I like that the leads r flawed n doing things they shouldn't do acc to society. Good they show a lead pair cheating on a now sweet lady.
We r sooo tierd of the perfect people, its nice to have a diff take.
