Hermione was sure no one would find her here – she made sure of it.
Leaving wasn't easy because there was everything to lose and nothing to gain – she would never again snuggle against him or drown in his mercurial gaze; never again will she be able to draw from his strength or taste his lips; she will never find out whether their could-have-been children looked like the ones she fantasized of having.
Most of all… she'll never see him again.
Hermione had made 'here' her home.
Then again, a home is in its people.
And hers will always be Draco.
