I'm not sure specifically which 'the last bus true story' you are referring to. It could be about a real - life incident that happened on a last bus, perhaps involving some interesting characters, a strange encounter, or an event that made it a memorable journey for those involved.
It's a bit of both. 'Last Bus' takes some cues from real events and blends them with fictional elements to craft a unique narrative. So, it's not purely real nor completely made-up.
The 'last bus real story' could potentially be a story of hope or despair. Maybe there was a person running late for the last bus and it was a matter of great importance for them to catch it. Whether they made it or not could lead to different outcomes. It could also be a story about the community on the last bus, how different people from different walks of life come together for that short journey and what kind of interactions take place among them.
