I was actually one of the posters who said that the girls deserved his revenge.
Now I have to say that he is going on too far.
Gunjan on the other hand, is not being smart at all. The reason behind her doing all this is very weak and truly is illogical. Besides she needs to see that she is hurting Rachna more by playing along with Vihaan than if she were to speak the truth. Does she think that Rachna has no pride to take back the guy who broke their engagement on the day itself to engage her cousin, then announce and parade Gunjan to everyone at the college? Come on Gunjan, you are smarter than that!!
She should realise by now that he has no intentions of marrying Rachna. If he had then he would not announce his and Gunjan's engagement to the college. After all, will he say that he has changed his mind about marrying Gunjan after one week? And why would Gunjan want that for Rachna anyways?
So now I think it's time for Gunjan to be sensible. Sadly though I have a feeling that the CVs have purposely made her dumb to redeem Mayank by having him solve the mystery.
While that is all well and good, I still do NOT want him back with Gunjan!!
