End The Madness

Reed and Y/N had been best friends every since Reed was 4 and Y/N was 3 years old. They were practically inseparable. They did almost everything together. Later, on Y/N's 17th birthday, everything started going downhill. Reed was doing something terrible, and Y/N had to stop it. The world would die if she didn't.

Will Y/N save the world from Reed's madness or will she become the madness?
