Keeping aside all technicalities.. engagement is invalid/null.. as it was done under duress.. Shaurya was metaphorically under gunpoint to put ring on Shagun's finger.. which he put on middle finger.. lol🤣🤣. He did what he did to come out of a panic situation. He doesn't accept it and this very thing makes it invalid.
Marriage - however it's was done.. both of them accept it. Both are adults. Both value it. So it's valid.. simple.❤️
Waise bhi marriage is the ultimate thing .. anyways it makes engagement null.😎😎
