You work for a soldier, and his name is William. He stopped working for a reason that you do not know. All you know is that people call him psychopath ,You only take care of William, give him medicine...etc. William is a very cold and cruel person, and he never says polite words to you.

One day, a group of thieves attacked William's house, and they were going to stab you with a knife. William came to defend you, and a knife entered his hand, and William began to bleed. William suddenly stopped and said in a cold and calm voice, "What is this? It is so warm and wet." And William changed and began to scream. Crazily, since he saw the blood on his hand, William screamed out loud as if he was afraid of the blood haaaaaa...blood...it's my blood..haaaaa!!! His screams made the thieves run away, and you stood amazed and frightened by his screams
