You never thought anyone would notice if you used the school computer to goof off and play video games. As punishment, you were sucked into the computer and turned into a web browser. All memory of your existence was erased from the outside world; nobody even remembers you. You're all alone inside the screen.
There's just one way out: you can try to communicate with the person using the computer. All you have to do is wait for someone - anyone - to click on your desktop icon. To use you, and not some other app, as their browser.
You've been here for almost a year.
