[Seoul - 2117 - Facility .03] A girl wakes up in the middle of the night only to find herself in a place she doesn't recognize. Although she can't recall anything from her past, she feels as if she has forgotten something very important. She then finds a boy in the unfamiliar place. It seems like he doesn't know anything about his past too, just like her, just like all the young people in the facility. He's not like the others though, everybody says he's... crazy, out of his mind. The only thing they remember is the tick tock of a clock before the complete darkness. The tick tock of their lives.
