The day of the festival is here, and the three are getting ready for their performance.  They sing, dance, and play on stage with all their hearts, and have the best time of their live.  But the wonderful fun they had leaves them sad and uncertain about the future.  And that night, Haruki is faced with a sudden and important choice.
Then I wouldn't get to 
enjoy watching you sleep.
Dann hätte ich dir nicht so schön 
beim Schlafen zusehen können.
Entonces no hubiera disfrutado 
viéndote dormir.
Porque no podría haber 
disfrutado viéndote dormir.
si je l’avais fait, je n’aurais pas pu 
contempler ton visage endormi.
Daí não ia poder te ver dormindo.
