It was released on September 28, 2005, nearly two and a half years since Mizuki's last single, "Shout It Out" (2003).

The title track was produced by Asian2 and written by the band's two MCs, 20 and Tatsu.

It served as theme song for the film Tobi ga Kururi to, starring Mizuki herself.

CDJournal described "C'est la Vie" as a "lively and cheerful, brassy and rhythmic track about believing in yourself.

"[1] The B-side, "Sweet One Week," is a cover of a Koushoku Jinshu song of the same name, from their debut studio album Akarui Mirai Keikaku, and is performed by Mizuki alone.
