[1][2][3][4] Shortly after winning the first Pocari Sweat Image Girl Contest in 1986, Moritaka moved from Kumamoto to Tokyo to begin her entertainment career.
A team of songwriters led by Hiromasa Ijichi (using the pseudonym "HIRO") and Hideo Saitō were brought in to compose materials for her debut album (also titled New Season), as she had not yet experimented on writing her own songs.
[5][2][4] In the music video, as well as earlier live performances, Moritaka played percussion and the keyboard solo; she has since focused only on vocals on the song.
The single was re-released on mini CD format on March 25, 1988, with "Overheat Night" replacing "Period" as the B-side.
Moritaka re-recorded the song on vocals and drums and uploaded the video on her YouTube channel on December 22, 2012.
