[Machine Translation] Promise", the second single from the debut of Mainozora, is a song about lost love that reminds us of nostalgic Showa-era songs. A distant summer memory, an unfulfilled promise. The coupling song, "Kareha-ro (Let's go home)" is a comforting song that embraces the small regrets and wounds that everyone has. The soft voice of Mainozora wraps up the tiredness of the way home. With its pastel-like simplicity and transparency, this song is a must-listen for 80's idol/new music fans!
