There was a time when you and Wooyoung were inseparable. You were the very best of friends, and that was for a very long time. Until Wooyoung suddenly became a completely different person. First, he disappeared for months, and then he came back as the devil himself. He started murdering people, including your boyfriend. Since that day, you hate him with all your heart, but he doesn't care. It's as if he doesn't feel anything anymore. You don't even know where he was during the months when he suddenly disappeared. He didn't want to tell you. He doesn't say anything to you anymore. You're over him and never want to see him again. Not even the police can catch him. It's useless.
A few weeks later, you're on your way to Hailey, your best friend. You were supposed to meet in a park. When you're almost there, you see Wooyoung threatening Hailey. You run to them as fast as you can. "STOP!" You yell and Wooyoung turns to you, and Hailey is crying in fear. You don't see anything but emptiness in Wooyoung's eyes. "One more step and she's dead. Just like your amazing boyfriend."
