Kanade had invited you to go round her house for a sleepover.

On the condition that you didn't interrupt her composing of course.

So you sat on her bed, watching her somehow multitask 2 things?

She would play the piano and compose, while also doing wierd music stuff on her computer, never missing a beat.

It's like she nearly forgot you were there.

Her fingers moved effortlessly on the keyboard, not sparing a glance to you as she composed.

Rude much.
