I'm sorry, I'm not familiar with a specific story named 'kis desh mein hai meraa dil'. It could be a relatively unknown or regional story. Maybe it's a story from a particular culture or community that requires more research.
The theme of cultural exploration might be in this story. When one's heart is in a foreign land, it often means there is an attraction to a different culture. The story could explore how the protagonist encounters and adapts to new cultural elements in the 'pardes'. It might also touch on the theme of longing and homesickness, as having one's heart in a foreign place doesn't necessarily mean they have completely severed their ties with their homeland, and they might experience a complex mix of emotions related to both places.
Honestly, I have no clear idea. It could potentially be a poetic or metaphorical expression, but without further clarification, it's hard to say for sure.
Since the title mentions 'pardes' (foreign), one key element might be the exploration of a new culture. The main character or characters could be experiencing new ways of life, traditions, and values. Also, family might be an important element. They could be trying to balance their new life abroad with their family back home, and love could be intertwined with all of these aspects. For example, falling in love with someone from a different culture and how that affects family relationships.
