- Mikako Nagamine: From now on, it will take eight years and seven months to receive each others' mail... Sorry... Say, we are separated by space and the Earth... like lovers... like lovers, aren't we?
- Noboru Terao: The mail from Mikako had only two sentences, But even with only this, I think it's like a miracle.
- Mikako Nagamine: We are far, far, very, very far apart... but it might be that thoughts can overcome time and distance. Noboru, have you ever thought about something like that? If...
- Noboru Terao: If for even one instant, something like that could happen.
- Mikako Nagamine: What I would think?
- Noboru Terao: What would Mikako think?... there is probably one thing we would think.
- Mikako Nagamine: Say Noboru, I Am Here
- Noboru Terao: In this way, my first quarter at high school passed by while exchanging mail with Mikako.
- Noboru Terao: [looking at mobile phone: No message has been received] The further Mikako goes from the Earth, the more the time it takes to exchange mail lengthens.
- Noboru Terao: [Again looking at mobile phone: No message has been...] It's just that... I will become someone who only waits for Mikako's mail.
- Noboru Terao: The time between Mikako and I drifts further and further apart. That is why I have made a goal: to make my heart harder, colder and stronger. The door that I know will never open. I won't knock on it eternally. I will become an adult, even alone.
- Mikako Nagamine: I want to be hit by the rain, I want to go to a convenience store and eat ice cream together... Noboru... Noboru, who's become 24 years old! I am the 15 year old Mikako and I... you know, I really like you.
- Mikako Nagamine: You finally came this far, didn't you? To become an adult, pain is necessary too, but you will probably be able to go much, much farther, even to other galaxies and other universes.
- Mikako Nagamine: You know, Noboru, I have a lot of things I reminisce about, After all, I have nothing here. For example, you know: For example, things like summer, clouds and like cold rain... Things like the smell of a fall breeze. Like the sound of rain drops hitting an umbrella... Like the softness of spring soil... Like the feeling of peace at the convenience store in the middle of the night... And then, you know, like the cool wind after school... Like the smell of chalkboard erasers... Like the sound of a truck passing by in the middle of the night... Like the smell of asphalt in the rain... Noboru, Things like that, I have all this time... All this time...
- Noboru Terao: I thought that I would like to experience these with you, Mikako.
- Mikako Nagamine: You can take a picture of something and it never does it justice... I think about that sometimes when I see a picture of you...
- Noboru Terao: It's stopped raining, hasn't it? Hey, look The sky It's a Tracer. It's pretty, isn't it?
- Mikako Nagamine: Yeah... Say, Noboru... You know, I... I am going to be onboard that.
- Noboru Terao: The seasons have passed once and summer has come again. It was the winter of last year that I quit waiting for mail from Mikako.
- Noboru Terao: Since middle school, we probably only saw each other... But a distance that takes eight years at the speed of light, is no different than saying, ''forever.''
- Noboru Terao: That summer day, I remember well when I thought the period of eight years seemed eternal. Although I haven't lived my life since then without indecision, that goal I decided upon that day still hasn't changed. I will live in my own time.
- Mikako Nagamine: Until middle school, I thought the "world" was where cell phone air waves could reach.
- Noboru Terao: The time gap between Mikako and I will only widen. So, I made myself a resolution. To harden, cool and strengthen my heart. To stop knocking on the door that I know will never open.
