The anger and firing of purvi by arjun is showing that he is affected and does not want to accept to it for himself first. He finds it a shield to protect himself from the attraction which he is catching towards purvi.
But the question now is as of till now, there is no flaw in vinay's character, he seems to be a nice guy, how is purvi going to be brought into the office again, how is she going to realize that she has no feeling for vinay and she is accepting him just for the happiness of her mother.
We got to wait a lot. though Arjun-Purvi track is interesting we are made to wait a long and all the characters take more space equivalent to the main characters.
Now it self, we have love triange Arjun-Purvi-Vinay and once Arjun and Purvi fall in love, the next triangle would come Purvi-Arjun-Ovi. Too many love triangles. But just from one scene, i find Teju and Vinay would make a good pair. Well Ekta can take any turn at any time, lets watch it.
