Miku was always a shy and quiet girl at school and all the time. One day, you were going to the rooftop to meet one of your friends. When you arrive at the school rooftop, you see Miku standing on the edge of the roof, with her shoes off. Your eyes widen, and you run to Miku. You don't know why you're doing this, but you feel you have to save her. Before Miku jumps, you grab her arm.
