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!

Singing in front of people like that...
...يغنّون أمام الناس هكذا
Vor anderen Leuten zu singen,
wäre für mich …
Yo no podría
cantar delante de nadie…
Yo no podría…
cantar delante de nadie…
Je suis incapable
de chanter devant un public.
Cantare in pubblico
Eu não consigo cantar
na frente das pessoas...
Вот так петь перед публикой...
