The significance could lie in the contrast presented. 'Devils' often represent chaos or immorality in literature, while a'realist' is more grounded. In an old love story, this could mean that the love is between two very different characters. The story might explore how they overcome their differences or how their relationship is affected by their opposing characteristics. It could also be about how love can exist even in the face of such extreme differences.
The 'devils' in 'devils guard the real story' are very much a mystery without further context. They could be the product of a creative mind's imagination, designed to add an element of danger and mystery to the story. They might be inspired by traditional devil - like figures from mythology, such as Lucifer in Christian mythology, with all the connotations of evil and temptation. Or perhaps they are a new and unique creation within the story, having their own set of characteristics and motives that are yet to be discovered. Maybe they are not even living entities but rather some kind of inanimate objects or forces that are personified as 'devils' for the sake of the narrative.
Well, the main characters would be the devil - like figure and the realist. The devil - like character could be someone with a sense of rebellion, perhaps with a dark past or a different set of values compared to the realist. The realist, on the other hand, might be someone who values stability, honesty and hard work. There could also be some secondary characters, like a wise old mentor who tries to guide them in their relationship or a jealous rival who tries to come between them in this old love story.
The Devils Tower story is typically regarded as fictional. It might be based on some elements of folklore or imagination, but not based on actual facts.
