Once upon a time, there was a girl who went by 004... ~~~ A new teacher is covering class- a strange substitute, who seems to know more than she's saying. Meanwhile, many years ago, a girl named Four grew up in a lab... And now the murders are happening, and to her, this all seems VERY familiar. Like the doing of a man she hasn't seen for a very long time... (Henry Creel/001 X OC. Bit of a slow-burn. Sort of enemies-and-lovers. Dark.)
