They know they cannot be together, but both have their separate reasons. Rosaline is an exiled princess with hidden magic, if she tells anyone about her feelings, her friend will be targeted. Sebastian believes it has to do with their societal ranks, with him forever destined to be a knight serving a royal.

They encounter difficulties when an assassin targets their kingdom in Galaonnor, with more and more secrets being exposed. 

"The Moon and Her Star" comes from both of their roles in Galaonnor. Rosaline was born on a full moon and was bestowed the name "Moon", which has been used as an insult towards her. As a result, she considers Sebastian to be her North Star, making her nickname endearing.
