Well, I haven't come across any definite confirmation that Meri Guriya is based on real events. It could be inspired by various elements or completely fictional.
The 'hum saath saath hain fanfiction' can be special because it allows fans to explore different scenarios and relationships that were not fully explored in the original work. It gives a chance to expand on the characters and their stories.
As I don't know the 'meri maa serial', I can't tell you the main characters. It could have characters like the mother herself, her children, her husband if it's a family - centered story. There might also be neighbors or relatives who play important roles in the story.
Well, sort of. While it has elements drawn from reality, it also incorporates fictional elements to enhance the narrative and make it more engaging for the audience.
