Riu Domura's new song "beautiful days" will be released on January 10. This song, the eighth song in a nine-week series of new song releases, has the message of walking at your own pace, if not running, toward your dreams. It is a positive song that says it is cooler to fail than to let your dream end as a dream, and it is a song that pushes people toward their dreams. This song's beat is produced by Omamurin.
