Rin discovered something unexpected....

Kagamine Rin

Hm? What's that sound coming from Miku's room?

Hatsune Miku

Oh! Rin! I-I didn't know you were home...

Hatsune Miku

(Please don't let her notice anything suspicious!)

Kagamine Len

We were just... practicing a new song! Right, Miku?

Kagamine Len

(Why am I such a terrible liar?)

Kagamine Rin

Oh really? Must have been quite the duet...

Hatsune Miku

Rin! It's not what you think!

Kagamine Rin

Don't worry, your secret's safe with me~

Kagamine Rin

But you might want to be quieter next time you 'practice'!
