Mone Kamishiraishi, who celebrates the 10th anniversary of her singing debut on October 5, 2026. She releases a work conveying "thank you" to all the fans who have supported her 10 years of singing activity and to the people she has met along the way. The songs included on the album are each currently being created with "flowers" as their motif. Kamishiraishi, who says "having a song provided to me feels like being entrusted with one life at a time, flower by flower," creates the songs together with the artists she met and who supported her during her 10 years of singing activity. Carefully facing each single flower entrusted to her and bundling them into a bouquet, it becomes an album that is a bouquet of gratitude to everyone who listens. Among those who provided songs are Motoki Ohmori (Mrs. GREEN APPLE), GLIM SPANKY, Sakura Fujiwara, and other illustrious names.
