The villian of beyhadh, you can also consider her as a main character had done marvellous acting and her plot was the superb. Her character was shown as cunning, egoistic girl who should always get what she wanted and never want to loose no matter what happens.
Hero's character was more often regular to fall in love with the heroine and get along with it. But in this show it was opposite hero married the villian and she succeeded about to achieve her love. Her enormous amount of love couldn't let hero to getout of her sight, though later on hero and heroine get along and married couple gets divorced and later it becomes a revenge story.
The plot and story line is just awesome.
Do view this show atleast for once.
