Elise is an unemployed woman from the modern world and she transmigrated to the book "The Lazy Lucky Princess." She hated the book because of its cliché plot and the unexpected dark past of the protagonist-Alicia, an orphan who eventually became the Saint of the Empire. Alicia is a lost noble but because of her kind and intelligent nature the people naturally love and praise her including Elise.
When Elise wakes up in the body of the child and realizes that she was reincarnated to the book she lazily read, she struggles on how to survive in the other world and somehow meets the characters and be acquainted with them. She tried to change the flow of the story but the events became more dangerous and Elise was reminded why she hated the original plot.
Then Alicia reaches her fifteen birthday. The unexpected things happened when Elise was bleeding in the same spot Alicia had her wound. Elise also has the golden light just like the divine power of the Saint.
