Good Thought...
Infact, I was thinking exactly same yesterday, after I saw, that Vinay looking around for Purvi, and Tej saw this, and with non verbal communication, indicated to him, "Wait, I will go and check inside"
Lol... and she moves out!!! :D
But honestly I also find, Purvi and Vinay Cute, He cares a lot for Purvi, and any normal, simple girl like Purvi deserves man Like him...
And Being this serial, am sure, that they won't just break the jodee, for no reason, so Purvi can be with Arjun, they will show some scenes, which will lead to Purvi's heart break, and Arjun mending the same... or something...
I still remember the storylines of Kahanii, had abrupt breaking of engagement of Gayatri and Sameer, so Sameer is with Shruti... It was bad way of showing, break up!! where audience would feel it was Shruti's fault!!! :( :(
