I'm not sure specifically as I haven't read this novel. It could potentially be about the interplay between light and shadow in a symbolic or literal sense, perhaps with characters named Ryu and Hyang experiencing various events related to these concepts.
A common theme is heroism. Ryu Hyang often has to face difficult situations and emerge as a hero. Another theme is exploration, as he might explore new lands or magical realms.
The Legend of Chun Hyang goes like this. Chun Hyang was from a humble family but had a pure heart. She caught the eye of Mong - ryong. Their love story began and they tied the knot. Then Mong - ryong went off to the capital for his studies. In his absence, the evil magistrate came along. He saw Chun Hyang's beauty and wanted her for himself. But Chun Hyang was a strong - willed woman. She wouldn't give in to his demands. This led to a series of events where she was in peril. When Mong - ryong finally came back, he used his new - found power to rescue Chun Hyang and make things right.

I'm not sure specifically as I haven't read it in detail, but generally, in many novels with 'light and shadow' in the title, themes could be about contrast, like the contrast between good and evil, or different aspects of a character's personality.
I'm afraid I don't know the specific main characters in this novel. However, if it follows common patterns, there might be a character who starts in the 'shadow' - perhaps a character with a troubled past or a difficult situation. And there could be another character or a group that represents the 'light', like a source of hope or a positive influence. As the story progresses, their interactions might be central to the plot, with the main character(s) evolving in relation to these opposing elements.
One of the main themes could be the struggle between light and dark. The title itself suggests this duality. Another might be the journey of self - discovery for the characters. They probably face various challenges that force them to understand themselves better.
