Patients Zero (Dramione)

-Post Hogwarts-
Everyone is born with a timer that counts down to a major life event but they aren't told what it is.
One day, Hermione Granger is walking home when she realizes her timer is almost to zero.
That same day, Draco Malfoy is transferring a new potion from his company that's about to be tested when he gets distracted by his own watch.
