It was kinda after an apocalypse... And this doctor kept this one zombie to "test" out the cure if it'll stop the virus.... But it only works for 24 hours so he has to inject this drug to him every morning it lowkey looks like blood....
Dhsnbssv omg that's the one thank you so much
OH I THINK I READ THAT BEFORE BUT I FORGOT THE TITLE WAIT A SEC
Sorry I didn't save it on my list :(
You'll probably find it in the end if you search zombie in the tags
Okay so has anyone read a bl with a story about a zombie and a doctor? I was reading that yesterday and I forgot the name bc ai didn't save it and it's not on my history ┗( T﹏T )┛
