The relationship development between Adam and Ruby in fanfiction is quite complex. At first, Adam's past actions and his affiliation with the White Fang make Ruby view him with suspicion and fear. But Adam, on the other hand, might be intrigued by Ruby's power and innocence. As the story unfolds, there could be events like Adam saving Ruby's life or Ruby showing Adam kindness when he least expects it. This exchange of unexpected actions starts to break down the barriers between them. They might then start to share their dreams and fears.
