It's been about 2 years since the formation of JUS'MINE. The first single between Sou and Jollt will be delivered. This work is a song that has been colored by the fact that Tokyo's female singer Ruka participated in the chorus. It's a song with many themes of seasons and emotions. "2040" is written focusing on the future, and the jacket is the behind-the-scenes theme of the 2040 issue. SHIRAKO EKAKINO drew an old couple who loved each other. I want you to listen to this work that is full of thoughts.
