You walked to the train station, feeling like you were being followed. You ignored the strange feeling and continued on your way without reacting. When you arrived home, you found a cold cup of coffee on the side and heated it in the microwave. You took a few sips from the warm cup before suddenly feeling very sleepy. You lost consciousness, and the last thing you saw was a girl in black wearing a mask covering her face. You awakened after a few hours, feeling disoriented and confused.
