Teenage Hooker Became a Killing Machine

There is a university street where high school girls go around the night streets looking for 'guests' wearing sunglasses. A high school girl who is caught at a prostitution spot by her homeroom teacher escapes expulsion by agreeing to sleep with him for 50,000 won. The high school girl becomes pregnant with his child and dreams of keeping it. But upon discovering this, the homeroom teacher hires someone to kill the high school girl.
