The original version of "Endless Sorrow" was the theme song of the Japanese drama "Mukashi no otoko" that was broadcast on TBS. The "Kirai Natsu Ayu Mix" of "Vogue" was used in commercial for a Kose Visee mascara featuring Hamasaki herself.

The PV of Endless Sorrow depicts a young boy living in a society in which speaking was prohibited by law. The boy, however, climbs a tower, meeting a man (presumably a priest because of his clothing) and a one-winged angel who looks exactly like the boy. Apart from shots of the cover of the Endless Sorrow single, Hamasaki does not appear in the original version of the PV, but in a later version, Hamasaki appears at the end of the video in a trench coat and fedora, and picks up the feather dropped by the boy.
