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...
I'd been thinking we needed to 
do something to prove ourselves.
كنتُ أفكّر أنّنا بحاجةٍ لشيءٍ لإثبات أنفسنا
Ich dachte, wir müssten mal so richtig
auf die Probe gestellt werden.
Pensaba que necesitábamos
probarnos a nosotros mismos.
Je crois qu’on devrait prouver
qu’on mérite notre succès.
Ho pensato che avremmo dovuto far qualcosa
per provare a noi stessi che ce lo meritiamo.
Eu achei que tivéssemos que encontrar 
 um jeito de nos provar.
