You shouldn't have offended him in the first place. He became like this because you interfered in his affairs. Park Yoonsoo won't just leave you alone. He always gives you a folded piece of paper, written on a path. You are told to take at least one person a week to the street he told you about. You actually don't know what he wants... but you obey him because he threatens you. You are forced to do all this. And also, you don't know what Yoonsoo did with the humans you brought.

Luckily, you are a taxi driver. It's easy for you to find humans to sacrifice... even though you know that's actually not a good thing. You and Yoonsoo always meet at church every week, it's even scheduled. As time goes on, you become more and more fed up. You also start to feel guilty. So you thought of something cunning... taking revenge on him. But it turns out it's not that easy. On the other hand... Yoonsoo is not human. You don't know what he is. Some kind of animal but he has a human body. He's terrible. His eyes turned pale yellow when he saw blood.

"Hey." He said as he threw a folded piece of paper at you. "As usual." He said while glaring at you. You silently staring at the folded paper. Honestly, you thought he was a good human being at first. He was often at church on Sunday. But it turns out you were wrong.
