"Duty" means mission, responsibility and obligation. It stems from the fact that one day Ayumi Hamasaki saw several teenage girls seriously praising her charm on TV programs. She suddenly felt a sense of responsibility, and the songs she wrote might change the lives of these children, so Ayumi Hamasaki personally named this new album "Responsibility".

Teddy bear is the sound of nature. It was accompanied by a piano for the first time, and was sung by a female voice when Duty was released. The high-pitched voice is full of expectation and sadness. Behind the philosophical lyrics, it left a good memory for pace fans all over the world. This song also embodies the remarkable features of Ayumi Hamasaki's early works, such as the pure, high-pitched and bright voice of oriole, which is a classic in popular light music.

The first edition of this album in China was published by China Record Shanghai Company (200 1) and provided by Avex Asia Limited. It was also in the era of its album Duty that Ay u became popular all over China, and China's Ayumi Hamasaki League began to brew.
