Usually when they're done practicing and are cleaning up, Oikawa starts to sing songs.
They don't really mind, and iwaizumi's already used to it so he just sings along.
Makki and Mattsun are also usually seen harmonizing with them in the background from time to time.
It's only because they're bored but it turns out people work faster that way.
Because later they then get blackmail material, and a video of them singing which they normally wouldn't have.
