I saw most of the last episode, and I don't get this hate for Krish. He's really not done anything that's even half bad. He wants a chance with Priya--why not? He didn't pass on some info, I think someone said, but come on! Nobody is selfless. That doesn't take away from anything good he did, for whatever reason. Did I miss something significant that indicates creepiness?
(To digress a bit, it's so unrealistic that Krish even "liked" Priya, then helped her and hung around for 5 years...what, these tv guys have no natural urges? They just subsume those in unrequited lub? And what about between college and meeting up with R&P? He was a monk? I wish these people would flesh out characters.)
Nothing wrong in Krish wanting to propose, IMO. I put down the reactions to the crazy overprotectiveness fans feel towards the leads, thanks to experience with how third wheels turn toxic on itv. Hope that doesn't happen here, since there's enough crap going on.
