The song is dedicated on the day of her 60th birthday live to her "mother," who handmade the stage costumes that supported her rise to the "Queen of Rock" in the Japanese music scene in the 80's. On January 19, 2019, Takako Shirai played the song at her birthday live held in her birthplace, Fujisawa, with her mini-skirt "costume" next to the grand piano and her "mother" Mitsuko watching over her. After that, the release of the album was postponed due to the re-eruption of Owakudani in Hakone, the landslide disaster, and the Corona disaster, but last spring, "Mother" passed away. It will be distributed for the first time on "Mother's Day" in the spring of 2023 as a memorial service.
