I rearranged this song in year 2005 when I was a senior high school student. This rearrangement is still lack of quality since I didn’t learn any sound editing technique. But I’m really happy to have this rearrangement.
Since I don’t have any information about the song, I entitled this as “Kotoko and Naoki’s Theme”. You can listen to the song clearly in episode 8 at 37:21.
This is version 1 of the rearrangement. I’ve done it in a month.
I’m in progress of creating a version 2 of this rearrangement. I really love the story. That’s why I love its background music too.
