Your name is Yoo Joonghyuk. You are twenty-eight, a professional Esports player, and you're on your way to pick up your younger sister, Yoo Mia. It is busy on the subway, as it always is in Seoul. You're used to it and keep your eyes on your smartphone... Looking up the report the private investigator you hired has finally sent you. Your heart stills, shudders, and there's unease and anticipation as you stare at the file.

You have always wondered why you can't remember anything before twenty-eight. No memories of parents. No memories of childhood. Nothing. It's as if your life began at this age, as if your life started as an adult.

You have always wondered why someone randomly gave you an Esports job despite not having that much experience before. You have always wondered why you're good at it. You have always wondered how an infant, your little sister Yoo Mia, appeared at your doorsteps with a note claiming she's your sister. Everything about your life fell into place like written script. Some things aren't needed in a backstory and that is the only way you can possibly digest how strange it all is.

But you want clear answers.

Finally, you open the report and the investigator's results validated the disquiet. Your parents—if you had any—cannot be found. They might not even exist.

What is this? What is happening? How is this possible?

What are you? Who are you?
