I don't know the exact main idea as the title is so general. It might be about two characters who return to a certain place or situation that holds significance.
I don't know the exact main plot as the title is quite vague. It could be about two friends who went on a journey and came back with a great discovery.
The 'two came back true story' might be a story of survival. Maybe two individuals were lost in the wilderness or at sea, and against all odds, they managed to find their way back home. It could involve tales of their struggles, how they overcame hunger, thirst, and the elements. For example, they might have had to build shelters, find food sources, and keep their spirits up during the ordeal.
The 'two came back true story' is quite ambiguous. It could potentially be a story of two survivors. For example, in a natural disaster or some sort of accident, two people were the only ones to come back alive. It could also be a story about two people who came back to their hometown after a long time away, perhaps having overcome many challenges during their absence.
There are many such stories. Some involve near-death experiences where people were clinically dead but were revived. For example, there's the story of a person who had a heart attack and was brought back to life.
