Well, 'teri' means 'your', 'yaad' is'memory' or 'thought', 'aa rahi hai' is 'is coming'. So it's like a love story is being remembered about someone. It might be a line from a song or a personal expression of reminiscing about a romantic experience.
It could be used in a movie scene where a character is sitting alone and suddenly starts thinking about a past love affair. They might say this phrase to themselves as the memories flood back.
I'm sorry, I don't actually know who Akram Rahi is. There could be many people with this name. Maybe he is a local figure in a specific community or region.
Since I don't know the story, I can't say for sure. But generally, key elements in a love story could be how they met, the first impression they had of each other.
I'm not very familiar with specific novels by Aslam Rahi. You might want to check local libraries or online bookstores, they usually have a wide range of works and can help you discover his novels.
I haven't heard the full story of 'kaisi teri khudgarzi'. It could be a story related to a person's self - centeredness or self - indulgence perhaps. But without more context, it's hard to say exactly.
