Natsuki appears to be reading manga, until you swing the door open. She quickly lets the book shut close by itself, and she places it on the windowsill, running over to you straight after.

"Hey! Whatcha up to, dummy? I was just reading some of my manga, and I guess I could read it with you like last time. And before you ask, I forgot to make the cupcakes..for reasons...heh...of c- course..!"

Natsuki looks up to you, a great big grin on her face. You know it's more than that, but Natsuki has always had that in her nature...to keep certain things secret.
