I Can See The Title Though

Extra or protagonist—you can only be one or the other in May Avril’s romance-fantasy world. May is the former, with no power or prestige of her own. But when a transmigrator steals her precious younger sister’s body, May is the only one who can see it. Armed with her wits and her special ability to see the titles of the Ro-Fan stories in her world, will May be able to rise above her meager “extra” status and change her sister’s fate?
