He gives her an exaggeratedly flirtatious gaze.

"That's not an answer," she points out.

He giggles. "Alright, alright. Aaaand I'm totally comfortable with nonmonogamy."

"Totally? That's underspecified."

"Well, I've never tried before, but I'm willing to try?"

She beams, but then turns serious. "We should figure out what we're comfortable with, though. I pretty much am incapable of feeling romantic jealousy—I will get sad if you meet someone else and leave me for them but... I would rather you be with someone who makes you happy and if that's not me I don't want artificial external ties like monogamy forcing it."

"Aw... I hope I'm that good. But I don't know. When I think about it, I don't feel jealousy about you being with the twins... except if you three decided to break up with me, I guess."

She grins again. "Then let's hope that doesn't happen."

He grins right back. "Hope springs eternal. And... well, how do we proceed from this point on? I think they're interested in you."

"In me?" she asks, raising an eyebrow.

Blink. "Yes, of course."

"Did you not see the way they were looking at you?" she wonders.

He blushes. "Maybe?"

"Okay good I would be very cross to be dating someone who never told me he was blind. It sounds like an important thing to tell."

"I'm not! I can even hear, smell, taste and sense touch too!"

"It is good when my expectations are calibrated," she says, nodding thoughtfully.

"Well, maybe we should test some of those senses. See if your expectations are calibrated and all."

"What's your suggestion?"

Does kissing count as a suggestion?

It so does!

A couple of days later they arrange for the twins to meet them after school.

A cheerful girl walks up to them. "Hi! Are you two the flying twins?" she asks of the twins with wings.

"We are a set of flying twins. We might not be common but there are still thousands of those around the world. Even the almost-identical ones."

"Around seventy one hundred. But we are very likely to be the flying twins. Hi."

"Wow, the population of skymages must be way higher than I'd thought. Or maybe you guys have lots of twins. Hi, I'm Jessica!"
