ゆらぎの宇宙、恋と未来 (Yuragi no Uchuu, Koi to Mirai)

Background
A Swaying Love, World, and the Future is a song composed for the compilation album Kagamination ~Compilation for the future~. It's Hayakawa-P's first collaboration with Suzu, also his first collaboration project with other composers.

It tells the story of a boy (Len) who couldn't get together with the girl (Rin) he truly loves. He comforts himself with the fact that in a parallel universe, somewhere out there, another "Len" have a happy ending with Rin. With a heavy heart he accepts the fact that he could never get her, however highly believes and wishes luck to whoever "Len" in a parallel universe "gets" her.

This may or may not be a reference to Hayakawa-P's girl series; or any other Len original songs by Hayakawa-P; for many of Len original songs by Hayakawa-P involves Len not getting the girl he loves (E.g. Night Walker, the Girl Series).
