Since I have no knowledge of this 'ek rishta sajhedari ka' story, it's difficult to say the main plot. However, if we assume 'rishta' as a relationship and 'sajhedari' as some form of partnership, it could be about how they support each other, face conflicts and resolve them to make their relationship stronger.
Since I don't know the exact 'ek rishta sajhedari ka' story, it might be a story about a relationship (as 'rishta' can mean relationship in some languages). It could be about friendship, family or a more complex social connection. Without more details, it's hard to tell the full story.
I'm not sure as I haven't read it. But it could be about love given the word 'dil' (heart) in the title.
The main plot points include Archana and Manav's love story which is full of ups and downs. Their families' reactions to their relationship, especially the difficulties caused by Manav's family background. And Manav's attempts to build a better life for himself and Archana which includes his career challenges.
Since I don't have first - hand knowledge of 'ek jhoothi love story', I can only speculate. It could be that the 'jhoothi' or false part of the love story is a miscommunication. For example, a character might have misinterpreted a situation and spread a false rumor that impacts the relationship. Or perhaps one of the lovers lies to protect the other from something, but that lie eventually becomes a problem. It could also be about a false start to a relationship, like they got together based on false pretenses which later need to be resolved for the love to be true.
One main plot point is Archana and Manav's marriage. It sets the foundation for the whole story. Another is the family drama, like the issues with Manav's mother. Financial difficulties also play a big role. Manav's struggle to earn more money is constantly in the story.
Another option is to check with second - hand bookstores. Sometimes they carry unique and hard - to - find novels. You can also ask around in book clubs or on social media groups dedicated to literature. Someone in those communities might know where to find 'rooh ka rishta complete novel'.
Another option is to check with libraries that have a section for Urdu literature. University libraries or large public libraries in areas with a significant Urdu - speaking population are more likely to have it. If it's not available in physical form, they might also be able to guide you on how to access it electronically.
It could be that the 'haseena' has some sort of mystery around her. And the 'deewana' is drawn to this mystery as much as her beauty. The main plot would then be the deewana trying to unravel the mystery while also winning her heart.
The main plot points include Guru's life as an assassin, his falling in love with Aisha, Aisha's terminal illness, and the presence of a serial killer in the city.
I'm sorry, I haven't read this novel specifically, so I can't provide reviews directly. But you can try looking for reviews on Urdu literature websites or forums.
