Swedish producer Douglas Carr has worked on four albums so far since Eiko Matsumoto's debut in 1999. When he visited Japan in July 2019, he co-produced this song with Ryota Mitsunaga and Eiko Matsumoto. Douglas's backing vocals, vivid arrangements,Ryota's groove sense and Eiko's lustrous vocals come together to open a new door that has never been opened before. The addition of Takayuki Nishimura's Saxophone gives the song a more mature sound.
