The new boy ( I don't even know his name) is an enemy of Samrat and for that the new guy might try and talk to Gunjan and try to be her friend. This will make Samrat feel jealous and eventually he will tel Gunjan he likes her. On other hand Nupur might think the new guy is her Prince Charming or something and fall for the guy which means Nupur will get jealous of Gunjan. Nupur might tell Mayank that she thinks the guy is the one as he is her friend and Mayank will get jealous. And obviously the new guy will be Dia's new love intrest. This will cause fights between Nupur and Dia.
I was thinnking Samrat and Mayank can gang up together and do something about that guy ....
