The manga is a great visual representation of the story, but the novel allows for a deeper exploration of the world - building and character backgrounds.

One main difference is the pacing. In the manga, the action scenes are more visually striking and might seem to move faster. In the novel, the descriptions can be more detailed, which might slow down the pacing a bit but also add more depth. Another difference is in the character development. The novel may have more time to explore the characters' thoughts and emotions, while the manga has to rely on facial expressions and body language in the illustrations.

They may have different attitudes towards Sung Jin - Woo at different times. Some might be jealous of his growth, while others might support him. But overall, Sung Jin - Woo is the protagonist whose journey is the core of the novel.
