Summary:

This is a story about two friends, from nearly the beginning to almost the end of their lives, who happen to love each other.Tatsuya and Junichi are in 5th grade and their music teacher is a pedophile. One day the music teacher has a request for Yumi, a girl who uses him to get expensive gifts. He wants her to get Tatsuya into the music room so he can be with him. Junichi recently confessed his feelings for Yumi and she decides to use him as bait to get Tatsuya to go to the music room. Junichi and Tatsuya's future does not look good...Note: Only chapter 1 of volume 1 and chapter 7 of volume 2 is shotacon. Reading chapter 1 is almost necessary for the story and is not very explicit but chapter 7 of volume 2 is an extra/one-shot and can be skipped over completely for those who dislike shota.
