A new set of rules.

A new killer is lurking,

and is coming for you.

For what I have in store,

you can no longer ignore,

Figure out who I am,

and you just might be secure.

=================================================

Baek Seul Mi was sent to a special school under her parents authority for getting into too many fights with bullies.

Not special in a way it was a mental hospital, but special in the way that the school was made for kids who did bad things.

Terrible things.

Inhuman things.

Upon her arrival,

She notices there's only 14 people throughout the entire school building.

No teachers, No staff, No other students,

just them.

1 girl and 13 boys.

What's the worse that could happen?
