fill me in please

hey i know this may sound stupid..but why is kaveri after saloni and her family?! i really dont get that part..

Saloni's parents and Manno Bhabi forced samar to marry a rich, but spoiled girl who could bring a lot of dowry without knowing that he loves Kaveri. They wanted to use that girls money to get saloni married. fist samar agreed, but on engagement day he got married to kaveri and brought her home. narpat and Ambika got furious and insulted them a lot. One of them even slapped Samar in front of everybody. I think this is the only thing Kaveri is taking revenge of. She hates Saloni coz because of her samar agreed to marry a bad chractered girl. She is just too much. now everybody loves her a lot and samar's parents keep her as their daughter, but she still thinks bad of them.

yea..she's just weird like that..she hates the people who love her sooo much..
