So he is calling "Her" by name "Gopi" not by "Suno" "Are" "Tum" and many more.....
Its a good sign....hai na...
he is now not thinking her As A Stranger Any More....calling by names shows he thinks "she belongs to him" and he has right to call her by name....
*trying hard to not read more than this in his name calling*
chalo abhi "Tum" se "Gopi" and hoping soon "Gopi" se "Meri Pyari Gopi" bhi ho jayega.....
