The album was written by Masahide Hamada on lyrics, keyboard, trumpet, recording engineer, and mastering, with Kanta Wakatsuki on guitar, bass, and mixing, asu on vocals, and designer Yachi Shichijo on the jacket. The album was created by Masahide Hamada, who had lived in Beppu City, Oita Prefecture, during his college years. When he visited Beppu for the first time in a long time, he decided to create a piece of work based on the warm atmosphere of the city. The lyrics and sound that emerged from walking through the streets of Beppu with the steam caressing his cheeks are characterized by a gentle and warm sound, as if slowly melting in a hot spring. After the release of this work, it will be performed at Masahide Hamada's leadership live concerts at the famous Electrik Shrine in Roppongi and other venues.
