Well samar and kaveri had a love marriage. They ran away together to get married. Because the family wanted samar to get married to this other girl so that the dowry they would get from her, they could use to marry saloni off. But samar loved kaveri and they ran away and got married. And i think that is why kaveri hates saloni because she blames her for having to run away, and almost not getting married to samar. So basically she wants to hurt saloni, by hurting the family. LOL, she is weird!
