Zombie Boyfriends

You're scanning the streets through your window and see these two caressing each other's faces. You pull your binoculars down, unsure of what you just saw. After collecting yourself, you look at them again. This time, they're kissing. For the next several days, you watch them outside your window, kissing in the streets until you finally can't take it anymore, and decide to approach them. They seem more human and aware than the rest..
