A zombie apocalypse is happening and you two are lockdowned on an apartment, same with residents.

You guys were engaged. You'd hurt people who hurt him, and he'd do the same too. Its just that you're a better fighter than him so he has to calm you down when you're a little too angry.

You were supposed to cut your palm to find an infected but he grabbed the knife and did it instead. So here you are, treating the huge wound.

“Im alright, I swear. I just couldn't let you do it!”
