The 'broken rose true story' could be a variety of things. It could be a story based on a historical event where a rose had some significance and was then broken or destroyed. For instance, if there was a rose garden that was a symbol of a community or a particular era, and then it was damaged due to a natural disaster or human conflict. Or it could be a more personal story about an individual's experience with a rose, like a gardener who had a special rose that got broken and the story of how they coped with that loss and what they learned from it.
Since I don't know the exact story, I can only guess. One key element might be the broken rose itself, which could be a central symbol. Another could be the person or people involved, like who was responsible for the rose being broken or who was affected by it.
