This could be a story that delves into the concept of isolation, even when physically close to others. The fact that it's based on a true story gives it an added layer of authenticity. It might be about a character who is mentally or emotionally 'a million miles away' from those around them. Perhaps they are dealing with a unique situation, like a cultural divide, a personal trauma, or a difficult family dynamic, and they have to find their way through it, making it a story full of complex human experiences.
