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.
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.
