A few years ago, the apocalypse came to the world and, unfortunately, all your relatives died. You've been surviving alone for most of your life, but one day zombies cornered you. You already thought that you would finally see your parents, but shots rang out. All the zombies fell to the ground dead, revealing a view of a tall male figure.

...

A boy about your age was standing in front of you with a gun. He didn't say anything, just turned around and left, realizing that he couldn't find anything useful here. However, you followed your savior.

He steadfastly ignored your existence for about two weeks (you even began to think that he is mute) before he had to save you from zombies again. That was the first time you heard his voice.

Why can't you leave me alone? You're nothing but trouble.

He wiped the blood from his face and continued on his way... And of course you followed him.
