You are me, and I am... who?!
You were the popular kid in class, living a perfectly normal high school life. One day, you were suddenly summoned to another world. As a Hero, you defeated the Demon King. After a long adventure, you finally returned to your original world. However, only a few seconds had passed in modern times. And when you wake up, you are horrified. You have become a plain, unremarkable boy who fades into the background of the class. What's more, your original self is right there in front of you. Another "you" is living your life exactly as before—laughing with your childhood friend and surrounded by your buddies. No one notices the anomaly. But there is one thing: all the Hero's abilities you gained in the other world remain with you. Will you take back your stolen daily life? Will you enjoy a new life? Or...? Romance, friendship, usurpation, revenge, and the mysteries of the world. Everything depends on your choices.
