I just wanted to make a post about Sana's acting. As I think it is excellent. I always enjoy watching her. She brings this charm, emotion and playfulness to her character that I really like to watch.
I think Shravan is great too. And don't take this the wrong way but most people are always talking about his acting. I think Sana is worthy of the same amount of praise. Personally I think they are both equally great. The make a very beautiful and interesting pair onscreen.
Side note: I think Gayatri and David are awesome too and I wish they showed more of them.
