Temperance is in the same library. She isn't waiting or anything, but libraries are good places for reading almost by definition.

And a little paper airplane flies into the library through the door and lands on the same spot Kaede'd left the book.

Temperance checks to see if anyone is watching, then she picks up the paper airplane and reads.

Hello!
So this is a note. You asked me to write. So I'm writing it. I'll swing by tomorrow evening, if that's fine? Just write 'yes' or 'no' on the back of this envelope, the thing will fold itself and fly back to me.
—Kaede
P.S.: I never caught your name!

Temperance debates for a second and writes "Temperance. And Yes."

The note folds itself back into a paper airplane and flies away.

She is there the next evening.

So is he.

Well, she won't recognize that face.

She might recognise the truly excessive amount of lifeforce, however.

Yeah, but it takes a moment.

He can be patient.

She approaches. "Uh, new face?"

"Yep. Horrible condition I was born with, truly tragic."

"Alright. So, I have read the book and it's the most fascinating thing."

"Is it."

Temperance does not squee, but she does look like she wants to! "Yes, I checked some things, researched some other things. I think I even managed to cobble together something non-terrible."

There are dark circles under her eyes.

"Did you sleep at all?"

"I have slept in my life, yes."

He laughs and starts transferring wakefulness to her.

"Oooh, that is cool. How did you do that? How... did you do the entire thing?"

"What entire thing?"

"Go to another world and bring magic to this one?"

"Magical interdimensional bar stole a door, I went through it, met five amazing people who I'm now dating, their kind of magic is very infectious."

"I did not know what I was expecting, except 'not that'."
