"Save me, please..." the girl's voice persisted. She looked outside, where the young man seemed to be having a bit of trouble beating the teacher.
But after a bout of intense fighting, the young man outside successfully lured the teacher away and darted in, then swiftly and neatly closed the door behind him.
There was a loud "bang."
...He had locked the teacher out.
Yet it was not over. The sound of furniture being dragged echoed instantly; the young man, using some skill, broke the door lock and barricaded it with tables and chairs, completely blocking the teacher who was trying to unlock the door from outside.
The mad knocking continued outside, the young man took a breath, and then went over to check on the girl's injuries on the ground.
"Are you okay?" he asked, examining the girl's wounds. There were no serious injuries on her body, but numerous cuts and lacerations that continued to bleed, looking extremely horrific.
