I'm sorry, I'm not familiar with the specific 'ek prem kahani meri bhi'. It could be a personal story, a piece of local folklore or something else. Without more context, it's hard to tell the full story.
Rocky and Rani are two individuals from different backgrounds. Rocky is from a wealthy family with a traditional mindset. Rani is a modern and independent girl. They meet and fall in love. But their families, with their own set of values and prejudices, oppose their relationship. They face many challenges as they try to convince their families about their love. Through a series of events, including misunderstandings and reconciliations, they finally manage to get their families to accept their love and live happily ever after.
I'm sorry, I'm not very familiar with the specific 'ajab prem ki ghazab kahani'. It might be a relatively niche or regional story. You could try looking for it in local libraries or cultural heritage centers.
One common element is family. Family often plays a big role, either supporting or opposing the love. Another is the strong emotions of the lovers. They usually have deep, passionate love for each other.
Since I don't know the specific story, I can't say for sure what the main characters are. But usually in a love story, there would be a male and a female lead who are at the center of the story.
