What Is a Single Guardian Romance?

A single guardian romance is a story where one of the main characters (or both!) becomes the guardian of a child not their own. It could be a niece, nephew, godchild, or younger sibling. They’re often grieving, overwhelmed, or reluctantly thrown into the role. The romance unfolds as they navigate this new responsibility and find unexpected connection with someone who helps or challenges them along the way. Think forced proximity, emotional growth, and lots of found family vibes.
