Tenshi, Ei-chan, and Shiratori all attend Kawagoe Academy. One day, they get pulled into the orbit of former conductor Haruo. He drags them into his newly founded boys choir where they suddenly find themselves performing a song in front of an audience!

Oh, even now, 
I feel like I'm gonna disappear
حتّى الآن، أشعر أنّي سأختفي
Siento que voy a desaparecer.
Siento que voy a desaparecer.
Les saisons défilent malgré l’ennui
Ah, sembra sul punto di sparire.
Una stagione che passa di testa sua è vigliacca.
Даже сейчас мне охота уйти.
