I'm not sure about the main plot of 'Kora Kagaz' as I haven't seen it. It might be about the journey of a character or a group of characters in a particular setting, like a small town or a big city.
I'm sorry, I haven't actually watched the 'Kora Kagaz' serial in full, so I can't provide the exact full story. But you could try looking for detailed recaps on entertainment review websites or asking fans of the serial on relevant forums.
I'm not sure. It might be a phrase related to something specific or a combination of words that's not common. Maybe it's from a particular context or language I'm not familiar with.
