According to customs once your husband/fiance puts the engagement/marriage ring in your hand you cannot give it to anyone no matter what. Indeed many people do not remove ring once they have being engaged or married as it symbolises respect and love for your husband/wife.
I read in some report one colonel during WWII refused to remove his engagement ring in concentration camp even after terrible torture and germans cut off his finger to get that ring. That's how important your engagement ring is.
Engagement ring is usually worn in your left hand in the finger which has a vien that goes directly to your heart. It means both husband and wife are connected from the heart. Then why the hell Arohi removed that ring and gave it off like it is some small present from husband.
Obivously Arjun was hurt very badly.
Arohi must have told Dhondu she will make another such ring and get it for him tommorow. He anyways will not require it for a few more days. What was so much urgency. I guess both do not know the sacred meaning and value of engagement ring. Dhondu may not know custom as he is not married but Arohi must be aware right.
