The album semi-focuses on the theme of the number "two", with song titles like "To Too" (homonyms of two), and "In Duet" (of course, sung by two singers). In addition, there is a song called "Repeat" which repeats itself later in the album via the track "Repeat (Reprise)", and a song which is supposedly a sequel to the entire previous album titled "The Second Tides". The other half of the album doesn't follow this theme.
