Samrat is rehearsing with Gunjan what he wants to tell Sheena .. That is he wants to ask Sheena whether she can be something more than a friend to him .. Suddenly Sheena comes telling "Never" bcoz she would'nt like Samrat to fall for her .. As she is aware of Gunjans feelings now ..
I guess Sheena also is ready to sacrifice Samrat for Gunjan !
As she knows that Gunjan wants to move away from Samrats life for Sheena :)
That implies Sheena is positive !
