Rin: Len?

Len: Yes?

Rin: What are you singing?

Len: Kokoro Kiseki.

Rin: No, we're supposed to be singing my version.

Len: Why can't we sing my version?

Rin: Because your version is irrelevant and isn't even canon

Miku: *peeks into the room* Hey Len, ya need some ice for that burn?

Meiko: *is also there* OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOH

Len: Seriously?

Miku and Meiko: *are no longer there*

Rin: Well anyways, we're gonna be singing the original version

Len: Well what if I wanna sing my version?

Rin: Then you're gonna have to exit the premises.

Len: What do you mean--

Rin: EXIT THE PREMISES *drop-kicks Len out of a window*

--A FEW MINUTES LATER--

Rin: *relaxing* This is actually sorta peaceful. But I guess I should be practicing Kokoro. *turns on the music*

Kodoku na kagakusha ni

Rin: ... *epic facepalm*
