The world where humans with superpowers were born. Seo Haeryu, a superhuman who lived a life full of limits due to her uncontrolled superpowers, gets the chance to take the graduation exam just like everyone else with superpowers at the age of 19. There are a total of two rules that Haeryu must follow before graduation. First, always carry ‘hold steel’, a machine that controlled her superpowers. Second, wherever she goes, she should go with another superhuman friend assigned to her by the center. But the “superhuman friend” who appeared in front of Seo Haeryu doesn’t seem to like this situation for some reason… “Do you like me? I don’t like you very much.”
