Even though we all agree that it was wrong in reql life ... they planned it expecting all this... makers wanted to show some reasoning to VP marriage... hence this plot..
It is pretty clear they don't want even Sai question this... hence she calls him ex husband. It's clear they want to show VP as valid marriage.... 😔
That's the worst part. They used Sai to validate VP invalid shadi.
Whatever its n will be illegal, invalid shadi. No consummation clause se dissolve ho sakti hai, but kuch bhi logical nhi hoga naa
