The Ally 2nd single is a number created with the theme of the Tokaido Line, which was often used by members for commuting to work or school. One time I loved the music I listened to while commuting, and another time I took a train together in my youth and went to school with memories of love and dreams. And every day I aimed at my destination while talking with my friends on the train. I tried to express such everyday life through the Tokaido Line ~
