I find nishu has some sort of jealousy with kk. Nishu bonded with teja and tried to provoke her against kk which failed. He made both teja kk out of vip tag. He took simmba instead who wass doing nothing on the show.
When Rash came he asked whether kk ditched him or not she said no kk never ditched u. U ditched him . Nishu again shocked .
Now when Rash is bonding with teja kk umar, nishu hass problem with rashmi as well and took her name for jail.
Means whoever bonds with kk is a complete 'No No' to Mr. Snake Nishant
