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!

I-I don't want to sing in front of people!
!لا أريد الغناء أمام الناس
Ich werd niemals vor anderen singen!
No quiero cantar delante de la gente.
No quiero cantar delante de la gente.
Je refuse de chanter
devant quelqu’un d’autre !
N-N-Non voglio cantare in pubblico!
Não quero cantar na frente das pessoas!
П-перед публикой я петь не хочу!
