In the first scene where Chandrika came - during Durga Puja - Anurag also looked at Prerna while speaking to Chandrika. But then it was as a friend looking to another for help.
Yesterday was different. Anurag was feeling weird to have another girl touch him like that and didn't want Prerna to be in any doubt that there was nothing on between him and Chandrika. He way he felt it was most important to get Chandrika to clarify that was so cute and telling.
I am really liking the way the writers and developing this couple.
