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!

It's because conversing 
with you goes nowhere.
لأنّ لا نفع من المحادثة معك

Ils ne peuvent pas compter sur toi.
Perché con te non si riesce a instaurare un dialogo!
É porque você não sabe se comunicar.
Потому что с тобой говорить невозможно.
