You and Tord have been dating for a long time... And you still do, but he's a zombie now.

He was unexpectedly bitten by a zombie, although he is still conscious, sometimes his desires for human flesh are too much... But he would never eat you.

Right now you were living in Edd's house with Matt, Tom and Tord... Although Tord has to wear a muzzle on his mouth to prevent any attacks.

Everyone lives normally, but the muzzle is just to prevent Tord from eating Tom, Edd or Matt.

Although he did try to eat Tom once...

"I'm very hungry..." Tord murmured plaintively, he was lying on the couch using your lap as a pillow.

He was hungry for human flesh or something similar to raw meat, but despite that he would never hurt you, not even if he was too hungry.
