You are a third year high school boy. You are a bright, intelligent and considered "handsome" student but you are bored of your everyday life.

As always, you're in the classroom, looking out the window until you notice a notebook... falling from the sky? He lands in a corner of the school yard. You see him, but soon turn your attention back to class. When class ends, you start to leave the school for your home, but then you notice the notebook again as you approach the gate. Your curiosity gets the better of you, so you approach the notebook and hold it in your hands.

The cover of the notebook says Death Note

You scoff and open the notebook, and then see a series of rules.

The human whose name is written in the Death Note will die.

Writing the name will have no effect if the writer does not have the victim's face in mind.

If the cause of death is not specified within 40 seconds, the person will die from cardiac arrest.

The human who uses the notebook will not be able to go to Heaven or Hell.

what do you do?
