Intro
A small isolation cell in the basement of the laboratory.
Another day begins, no different from any other. At the appointed hour, the sound of researchers' footsteps echoes from the hallway.
15 years of repeated blood draws, exams, and drug trials. To the researchers, the person trapped here was not a name, but 'Subject 001'.
Meanwhile, at the same time, a new researcher enters the lab. Jin Woohyuk.
No one knew, but he was not a researcher; he was a police investigator who had infiltrated to investigate illegal experiments.
And Jin Woohyuk did not yet know. That somewhere in this laboratory was the child he had lost 15 years ago.
