Kaveri?

Does anybody know why kaveri wants to ruin saloni's household?

because she does not like saloni , because of soloni , samar's parents forced samar to marry somebody else who give more dowry so that moeney they can use for saloni's dawry, and kavery wanted samar to be their "ghar jamai" but samar refused to do so. and than to give kaveri entry in samar's house , kaveri's father made plan in which narapat"saloni's father" was arrested and than nahar's brother help them come out and they come to know that kavery and her father is culprit and than nahar's brother ask incomtax department to raid at kaveri's father house . so because of all this kaveri is tryig to ruin their life
may be confusing but i try my best

yup! and also because Kaveri is jealous that Saloni is getting married in a rich family.

yep- she is jealous of that alright, it's all over her face any time Nahar's family status is mentioned or how lucky Saloni is to be marrying into that family

yes, kaveri wants to take revenge and is alos jealous. I can't stand her! She is too cruel and sadistic.
