When i started watching ths show, i liked Atharva and Vikram...i thought what will RAvish get to this show...
But after he entered, i liked him too... at the moment i think both of them are good in their own space.
Atharva is mentally unstable and Vikram portrays it quite well.
RAvish is an army guy, they are trained to mask their emotions. So Shashank also plays it well, mostly we see it when he breaks down when he is alone.
Also His reason for not getting shocked on seeing Guddi's dead body, can be cause as an Army guy he is used to see people dead and also kill enemies. Dont you remember how he faced and killed so many terrorists when he entered. Quite possible he mustve seen a few on his closed friends dead bodies too, unfortunately. So that kinda makes the person hard and capable of handling the shock.
Anyways, my point being all the actors are good and doing a good job.
