I just don't understand?!

I just don't understand what's happened/happening to this show. I mean first Nupur dies?? I mean I was so shocked when she died, like how could she leave the show? And i mean if she died, then she would never come back. Second, they're are all these new kids in the college. I mean it's fun to watch what goes on with them, but i find it a little weird. Thirdly, Are Gunjan and Mayank going to fall for each other? Because that would just ruin everything! And lastly, I know whenever Samrat is with Ash, he always thinks of Gunjan. But is Ash really falling for Samrat?

i just don't understand what is going on with this show, I used to love it before they jumped 3 years. And by the way, what ever happened to Diya, Uday, and Benji??
