When I said I was falling for Harry I don't think you understood what I meant. I mean I'm literally falling for him. Falling to the ground. After all, there's probably no one in this world clumsier than me.
Draco breaks a time turner and starts jumping around in time (very similar to the premise of the Time Traveler's Wife). At first when he sees he's married to Hermione in the future, he's horrified and fights against it any way he can. But the love he sees in the future is unlike anything he'd ever imagined for himself. Meanwhile, his future self is coming to the past to charm Hermione. When they both meet up in the same time, things get fun.
