It is not Ranbir whose heart is made of stone, it's Kanya's. Ranbir already loved his family from beginning. He loves his Mom and BD. Doted on Aayan and seems really close to Aditya. Then he started caring for Suhaas and Adita. Pammi the mummy and Anand. He even gets along with Pooja and Harpal.
All the long bhashans Kanya gives about middle class people's heart. Beside her family who does she care about? She doesn't even seem to care about Aayan (not lovey way but I would expect someone to be a little tender toward the once love of her life). She doesn't even seem to care about Malika (who puts her before her own son)
So I would appreciate it if kanya didn't use these lectures. I liked the old kanya better. These Kanya has nothing to do. Except turn into natasha once a month. What happened to her dream of hotels? I am so bored with her character.
