トワイライトブルー (feat. しゅがーれいん)
One room, waiting for your return. Before dawn, under the twilight blue sky There are many small rooms in Japan and Korea, and this song depicts the sadness of loving a free person and the bitterness of waiting with the theme of one room. This song was born from the encounter between Shuga Rein, an artist living in Korea, and 8utterfly, an artist who has been active for 13 years. Arranged by Sugiyama Hokuto, the song is nostalgic and emotional.
