Author's comment (translation):
First, there're two of they, who are the indiscretionary "A" and the "B" keeping an eye on A. It's a song by B's view. I don't know if A realized B's feeling.
They are always together, one helps or counts on another when facing troubles, but somehow they are not able to be in love with each other. B did reckless things, and lost lots of things.—
It's such a story. I think that there're persons who have experienced that in all of you.
"If you hear a sigh in this song, it means you have an experience which had passed your own happy summer."
"If you hear a sigh..." = a parody on a sentence of "Through the Looking-Glass". However, I've never read that book...
