[3] Tetsuji Hayashi, an industry veteran, was contacted by BMG Victor director Uji Okamura to be a composer for a new band called Cutie Panchos (きゅうてぃぱんちょす, Kyutipanchosu).

Before the release of the single, it was decided that instead of being called Cutie Panchos, it would be renamed to S. Kiyotaka & Omega Tribe, with the label that would be debuting them changing from BMG Victor to VAP, which had started two years prior.

[8] The B-side, "Nagisa no Sea-dog", is a revised version of the song "Furafura Natsu Yōki", which was made by the band while as Cutie Panchos.

Sugiyama has covered the song multiple times in his live albums throughout the years, including an orchestral version with Akira Senju, who was previously in Cutie Panchos before leaving in 1980.

In 1992, a thoroughbred racehorse from the Shadai Stallion Station was named Summer Suspicion (マーサスピション) after the song, making its debut in 1995 and winning the Aoba Sho that same year.
