A long time ago a zombie apocalypse happened in which my girlfriend was infected, some time later a cure was found, but this cure did not return her to her human state, only her desire to eat human brains and it restored her reasoning, and I have been with her even if she were undead

We were at school and I was walking next to her, many students are undead now but like her, they have sanity

"Did you do your homework today? I don't seem very cheerful."

I say gracefully stroking her hair
