KUROFUNE made their CD debut through a special exception, but Keigo can't deny his anxiety and struggles to take hold of something that will establish them as idols. In the midst of all this, he overhears Yuto singing a song to himself and decides that that's the ticket to their future, but for some reason Yuto isn't on board...
Since I met the sound that 
always echoes by my side
لأنّي التقيتُ الصوت الذي يتردد بجانبي دوماً
Da ich den Klang fand,
der stets an meiner Seite widerhallt, …
Desde que encontré el sonido
que siempre resuena conmigo.
J’ai rencontré ces mots
Qui résonnent encore en moi
Da quando ho conosciuto la melodia
che sempre risuona accanto a me
