[Machine Translation] The second single from sacra, who made a strong debut with the single "Yesterday"! The song "don't look back" is a very comfortable song with a melody that gives a pleasant sense of speed in a world of sad poetry about people struggling to move forward. The coupling song "Endless Loop" is the opening track of the TV Tokyo drama "Hanpu no Tsuki ga Noru Sora", which is a live-action adaptation of the best-selling novel that sold 1 million copies in its eight volumes! The limited first edition includes a DVD with the video clip of "don't look back".
