As 'Kyunki Saas Bhi Kabhi Bahu 2' is all set to leap 10 years, actor Hiten Tejwani, who plays Karan Virani in the show, has spoken about the "most emotional chapters" and the harshest thing his character tells 'Tulsi maa', played by Smriti Irani.

After spending a decade behind bars, Tulsi returns to Shantiniketan, only to find the family she once held together deeply fractured. Her sons, Karan and Gautam, now stand on opposite sides, setting the stage for an intense battle of emotions and relationships.
