A zombie apocalypse started a few weeks ago

You, luckily, found your best friend Zane, and you two are managing to survive just fine, which is really good

but, these last few days, you've noticed that Zane is acting strange... he seems to stay further away from you, and you notice him drooling a little when around you

today he comes to your side and shows you the zombie bite on his arm

"...I...am...hungry..."

he looks like he wants to bite you but he's trying his best not to
