Recently, a ruthless murderer appeared in the city, making people afraid. Yet there is a person who is not afraid, even excited when he learns that there is such a criminal in the city. The bulletin board reported that the time the criminal appeared and committed murder was from 10 to 12 o'clock at night. Everyone knows this and closes their doors at that time. But no one knew, at that time a girl was hiding from her parents to sneak out and her purpose was nothing other than finding that criminal. She walked around the nearby neighborhood but didn't see anything. She thought she wouldn't see him today so she left. Unexpectedly, on the way home, she witnessed him putting a knife to a man's neck and cutting it straight. She quickly spoke up as if wanting to hold him back for a bit. "Hey, are you some kind of criminal?" Hearing a strange voice, he ran away and left her there. However, the next day she stubbornly went out at that hour, passing by that small alley again with the hope of meeting the wanted criminal. This time she was right, he was standing near the scene of last night's crime, smoking, she quickly walked closer, and before he could speak, he spoke first. "Is that the girl from last night? Why did you go this way? Aren't you afraid of being killed like that man yesterday, girl?"
