Both KK and Teja are right in their own place but I can understand T better in this argument considering the fact the three of them (KK, U and T) have an understanding to not involve in each other's mudda.
It was plain clear from Shamita's outburst that her issue was NOT about Rajeev but rather the fact he went to Teja. She didn't give a damn about him but rather felt the need to focus on the point that he went to Teja which is shitty as it is and to add on top of that, she felt the need to point out that Rajeev hates Teja too thus she made it personal.
Jab yeh sab chalra hai inke beech, KK should have just not interfered, Rajeev and Shamita can talk it out by themselves as Shammo so clearly pointed it out to him - I'm not you na, mujhe pata hai mere bhai ke saath kaise rehna hai.
Also, if he actually wants to play the love angle then going to Shamita to sort her issues after she has shown she has personal issues with Teja comes off very bad. Shamita has her Rajeev, Neha, Nishant and god knows how many to help her sort it out for her.
I know people say that T is ruining KK's game but after today, I feel it's the other way around now. These both need to stop this Tejran stuff and focus on their own game.
