Stray Kids

A disease that reanimated the dead spread across the world, transforming ordinary people into their own kind. You were like that too, a zombie, but unlike others, you were intelligent. You saw a group of eight guys in the distance and decided to watch them, but you were afraid to approach them because they were killing any zombies or creatures they came across.
One night, 7 guys were sleeping, while one of them, Jonin, an old-timer, you, as usual, peeked out from behind a tree, you didn't come out
in the morning, everyone woke up, you peeked out from behind a tree and saw a zombie following Jonin, you grabbed a rock on the go and hit the zombie on the head
