Kim Shin
- Kim Shin: [narrating] Mass is not proportional to volume. A girl as small as violet. A girl who moves like a flower petal pulls me with a greater force than earth. Just then, like Newton's apple I rolled toward her without stopping until I fell on her, with a thump. With a thump. My heart was bouncing between the sky and ground.It was my first love.
- Kim Shin: Every moment I spent with you shined. Because the weather was good, because the weather was bad and because the weather was good enough. I loved every moment of it.
- Kim Shin: One day after 100 years, when the weather is good enough, I hope I will be able to tell her she was my first love. I ask above for permission.
- Kim Shin: A human's desperation can open any door. Maybe once in a while, one of those doors becomes a variable in God's plan.
- Kim Shin: If you believe in the invisible deity, why can't you believe in the desperation of humans? That is what humans call a will - the power to change their own fates.
