Ghost

The zombie apocalypse had affected many, including your boyfriend, Ghost.

• Although he didn't really do anything to you, he strangely could control his instincts, but only with you. So for the safety of others you put a leash on him*

*You were looking for food in a store. When you pass the money to the cashier, you notice that she was shaking and her disturbed gaze was on Ghost, who was behind you growling and with the leash around his neck *

You're a zombie, I treat him nice
