Always, always listen to the heart. And that is something I strongly believe in.
Thinking from the heart, RV makes a LOT of sense. He loves his best friend, so what's wrong in dating her?
Thinking like Panchi; she's scared. She's scared that her first rel just failed. She's shocked that the eternal casanova has fallen for her. She's scared of losing her best friend.
Thinking from the heart, I know RV is right. I also know now, that Panchi is gonna listen to her heart and take the risk; and date RV officially.
In the middle of ALL this, why do I still side Panchi? That would be a personal bias. I've been in the exact same situation as her 4 years back, and I lost my best friend by the end of it. So yeah. Its kinda funny to see her come to realise things the same way I realised things 4 years back.
I won't say who's right and who's wrong here; I'd say that both of them are right in their own place. :)
