Sorry for being MIA, I haven't been KMKV actively these days, only on and off.
I see that quite a few things have happened. It is nice to see Priya and Arjun have developed feelings for one another but it obvious that Arjun has still hasn't come out of his dark past and experiences with Vandana. Thus, looking at Priya through the same lenses has he did Vandana after what has happened in past. He fails to realize that not all women are like Vandana and surely Priya is not like her.
At the same time, Biju and Priya are adding fuel to the fire by going overboard with their friendship. It is rather annoying to watch and unrealistic too. I find it strange that Priya considers Biju to be this "great childhood friend" but never once I heard her mention his name (unless I have missed it, if i did I'm sorry). Ithu logic illatha friendship --just my opinion.
