How? So a cousin has licence to do everything and get away easily.
And the man who thinks his wife dancing on her reception as harm to his izzat doesn't mind a woman sitting on his bed to feed him especially when she has feelings for him.
If it was modern family, I wouldn't have made a big issue of murtasim haya interactions.
But this is conservative family where woman aren't allowed to go outside alone.
In such family we have murtasim being ok with haya doing wife duties to him. No izzat tension for haya actions.
