This is one of their early representative songs, released following the huge success of their debut song, Sensei.
This single solidified Mori Masako's popularity during the idol enka boom of the early 1970s.
The song's melancholic, gentle melody and lovely, simple vocals leave a strong impression, and the lyrics, which depict the sadness of love against the backdrop of a sunset, highlight the pure charm of Mori Masako, who was still in her teens at the time. The song is filled with the lyricism typical of Japanese pop music, and it was a work that made her unique as an enka singer apparent from an early stage.
