"Emily, Isaac didn't ask you to go kill zombies. Just follow behind," another man named Henry intervened.

"All right, all right," Emily reluctantly agreed.

"Okay, you go get ready. We'll leave soon," Isaac said, and as soon as Emily left, Henry closed the door.

"Isaac, why do you insist on taking her with us today?" Henry questioned.

"You understand nothing! When we were taking turns clearing zombies before, someone was always here, so this woman seemed obedient. If we work together today, we can quickly clear the zombies on the bridge. Leaving just this woman here, can you trust her? Or do you think she's developed feelings for you after a few times together?" Isaac retorted.

"Of course not, it's not like I'm the only one!" Henry chuckled awkwardly.
