The choir heads into the mountains for a singing training camp, but when they arrive, they discover that the site they'd reserved is already being used by a rival school! Meanwhile, Haruo refuses to do anything but...look for kabocha squash?
I had so much fun, I ended up 
working through the night.
استمتعتُ كثيراً بحيث بقيت
مستيقظة في العمل طوال الليل
Vor lauter Spaß habe ich über Nacht
Me divertí tanto
que trabajé toda la noche.
He trabajado toda la noche.
Ça m’amusait,
et j’y ai passé la nuit.
Ero così presa che ci ho lavorato tutta la notte.
É tão divertido que acabei virando a noite.
Так понравилось, что всю ночь работала.
