He pauses the TV's autoplay and gently unwraps himself from her to get into his chair. "Preferences?" he asks, guessing the answer as he makes his way to the kitchen.

“Whatever you want is fine.”

But she can help with preparing it! She has this power!! And maybe she won’t even mess it up!! (That’s a lie, she probably will.)

"What's your spice tolerance like?"

"Uh." She doesn't know the correct answer to this question. "Fine?"

It sounds more like a question than an answer.

"I'll assume that means you've never tried anything with a real kick, then," he says with a wry grin. "We can have an omelette with kimchi, how's that sound?"

"Fine," she repeats, agreeably.

He didn't really expect any different.

Well, the silo is set up such that he can do everything from the wheelchair but it definitely helps to have her fetch stuff for him and he's pretty sure she'll be happy to be useful and to be given clear instructions on how to achieve that. Cooking is approximately the best possible activity on that front.

Yeah! She is so able to follow instructions, and seems to find this reassuring. It's hard to tell that she finds it reassuring, mind, but Woo-young has a lot of practice reading expressions entirely through minimal movement of eyebrows.

He super does! ...admittedly hyung's eyebrows are a lot more expressive than Hana's, but, you know, he's used to the language now even if the accent is new. Also a big part of reading it is knowing the person speaking it and that particular part of Hana's personality was very obvious very early.

"Had the bad luck to get a non-Euclidean A-rank today," he starts conversationally.

"Oh," she says, clearly not entirely sure how to respond to that. "I'm sorry."

"It's fine. They're a headache but they're interesting. I need to keep the map up all the time and it's twisty like a puzzle game, but my power does a lot better than a lot of other teleporters' at this." Really his power is one of the best teleportation powers out there, it's just his backlash that fucks him over.

"... The maps seem like they'd be confusing," she observes, after a pause. "Do they... twist into themselves? Can you only look at part of the map at a single time?"

Apparently Hana is capable of being nerdsniped. Or at least map sniped.

Bingo. 

"It really depends on the dungeon exactly! Like—have you ever played first person puzzle games like Portal or Antichamber?"

Nod! "Portal."

"So the technical name for dungeons that are mostly Euclidean except places connect to each other weirdly like they do in Portal is 'projective punctured space' but we call it 3.5D dungeon because it's, like, almost a regular 3D dungeon. Maps for those usually have two visualisations: a first-person 3D one, and a bird's eye view 2D one projected onto 3D." This is gonna be hard to explain without a visualisation so he summons a map of the most recent 3.5D dungeon he went to to explain. "None of today's were 3.5D, to be clear," he explains, "it's just a good starting point to get to the more complicated ones."

It turns out when Woo-young says that he "hates" non-Euclidean dungeons it's actually a love-hate relationship that he's very opinionated about. There are so many kinds of messed up geometries—spherical, hyperbolic, directional, embedded high-dimensional—and his power isn't great for all of them but it's pretty good for many, and although he doesn't have the maths background to understand the numbers underlying it all he's got a very good spatial intuition and understanding of them, which he uses the visual aids to supplement.

Hana listens attentively! This is actually really interesting stuff, and it's a wonderful distraction from her backlash. Being given tasks to accomplish is similar - it's mostly the decisionmaking that seems to cause her the most stress.

Well dealing with their backlases is the whole reason they're here, now!

...

"Do you... have someone else to help with your backlash?"

Blink blink.

"No?"

"So we should probably spend the night together." There's no way to deal with the rest of her backlash otherwise, if she doesn't have someone to fuck like he does hyung.

(It'd be easier if he could fuck anyone but hyung right now.)

"Oh. Yes, that would be fine."

"What are your assignment plans? Nightmare every day to the limit of backlash?"

Nod. "Yes. I'd like to arrive at an appointed time each day, so I can be scheduled around."

"If you're using Quasar as your intermediary they should have a suggested time for you on the scheduling app."

Nod! "Yes. I was going with that one."

Oh no, has she stated the obvious?? She's stated the obvious. She sounds so stupid.
