In a world where only one "Non-Awakened Returnee" exists, it turns out that I am the number one ranked little sister.
In a world inhabited by "Returnees" who came back after experiencing destruction and upheaval in another dimension, and "Awakeners" who gained special powers through a system.
Every "Returnee" becomes an "Awakener," except for me, Park Ha-young, the only "Non-Awakened Returnee." Living a life as an orphan, I suddenly discover that my real name is "Cheon Shin-ah" and that the number one ranked person in South Korea, "Cheon Shin-woo," is my biological brother.
Soon after, I awaken as an S-rank with fraudulent skills and abilities!
However, just as I'm about to walk a path filled with flowers, people who ask me to "stop the world's destruction" and those who threaten to "destroy the world for you" appear before me...
