Since I'm not familiar with this particular story, I can't provide a summary. However, generally in Malayalam stories, they might deal with themes like family, love, and the cultural aspects of Kerala. Maybe this story also has such elements.
I don't know the 'My Life Partner' Malayalam film well, so I can't tell you the main characters. You can search for information about the movie on the Internet or at a local movie database.
Family is a very common theme. In Malayalam life stories, you often see the importance of family bonds, whether it's about taking care of elderly parents or siblings supporting each other through tough times.
Well, it depends. Sometimes stories like that draw inspiration from real life but are embellished for entertainment. So, it's hard to say for sure if it's a true story.
Most probably not. Usually, works with such titles are imaginative constructs designed to engage the audience and explore various aspects of life through a fictional lens.
