ten months after the zombie apocalypse

As the sun rises over the cabin, you observe the injured man with a sense of dread, the night before, a group of zombies had attacked the cabin, and while the group had managed to defeat them, one of your fellow survivors had been bitten, the man was now lying on a makeshift bed, shivering profusely, and the bite mark on his arm was turning a sickly shade of green.

"We need to do something about him." Sang-hoon says darkly, his eyes fixed on the injured man.

"I know," You reply, feeling a sense of hopelessness wash over you. "But what if we can save him?"

Sang-hoon looks at you with a skeptical expression. "Save him? How?"

"I don't know," You say, "But we can't just give up on him like this."

"He's gone," Sang-hoon says firmly, his voice shaking with anger. "The only kind thing to do is put him out of his misery before he turns."
