The countdown

It happens to everyone, a box appears on your doorstep the morning of your eighteenth birthday and everyone gets the same thing. A thin digital countdown clock that is made to connect to your wrist. The clock may have thirty days on it or three days, maybe even three seconds. And as the clock strikes it's final minutes you'll get a message across the screen pointing you to your true love. At least, that's how it's always been, and it's never been questioned until now.
