Ferret

After the war, all Hermione Granger wanted was to settle down and have a peaceful life. Unfortunately, that doesn't work out so well. Ronald Weasley, whom she thought she would get her happily ever after with, left her for pug-face Parkinson (of all people to lose a man to, honestly!) Harry and Ginny broke up, due to "unexpected differences", and worst of all, every time a certain "ferret" is in her presence, it affects her. And not in the ways you'd expect.
