He or she might have a deep connection with the roses and through that, get involved in other events in the story, like meeting other characters who are also interested in the roses for different reasons.
Since I don't know the exact 'rose novel', I can't say for sure. But it could have a female protagonist who is drawn to the beauty and mystery of the roses in the story.
There could be a character who is a bit of an outcast in the story, and the roses are the only thing that gives them solace. This character might be at odds with the society in the novel, and the roses become a way for them to find meaning and connection. Another possible main character could be a poet who is inspired by the roses to write beautiful verses, and through his or her poetry, we learn more about the significance of the roses in the story.
