Saku, Sosuke, and Uta try to figure out a way to make money so Saku can go on the school trip with them. They make a song but it doesn't seem to be getting enough attention, so Kakeru helps them make a PV for the song to help promote it.
but you better not laze around the whole
time just because you're on vacation.
لكن من الأفضل لكم أن لا تتكاسلوا طوال 
.الصيف فقط لأنكم في عطلة
Aber nur weil ihr freihabt,
sollt ihr euch nicht auf die faule Haut legen!
pero no se vuelvan perezosos
solo porque estarán de vacaciones.
mas é melhor não ficar de bobeira
o tempo todo só porque estão de férias.
