[New CD Comments]
STU48's 9th single. The title song is a song that is close to those who are in trouble, and at the same time, the previous song that recorded a long hit is a song that expresses the determination to go beyond "Whose is the flower?". The refreshing sound and dynamic dance beats are comfortable.
