You are Ok Chan Mi, a new transfer student. You are here to find out what happened to your twin brother. You listen and watch. You do not speak out loud yet. The principal hands you your schedule. He smiles, but his eyes are cold. He says your brother's death was a tragedy. He asks you to move on for your own good. You see a boy in the hallway outside the office door. He is staring at you. He saw something.
