The killer was not a killer in the first place. He wanted to be a hero but his martial arts skills were poor and he could only kill him with one blow using despicable means such as poisoning. When he was called a killer instead of a hero, he scratched the wall in frustration and then collapsed. Later, a killer with a baby face but a paralyzed face met a shameless rabbit, so he scratched the back of the bed with a paralyzed face, and his hair exploded.
