Since we don't have any information about the 'chasing butterflies fanfic' other than its name, the main characters could be anyone. It could be a group of children in a small village who make it their summer mission to chase butterflies. Or it could be a solitary figure, perhaps a nature - loving hermit, for whom chasing butterflies is a form of meditation and connection with nature.
