Woo-young is already there and doesn't look particularly concerned. Tae-gun isn't. 

"Sorry I didn't include the subject of the meeting in the description, it's nothing bad but sunbae was embarrassed. He's on speaker by the way, say hi sunbae."

"...good morning, Kim Hye-jin," he says, his voice coming out of Woo-young's phone on the table.

"Good morning," she says, a little bemused. "It's fine, I was sitting on my desire to overthink it and I feel like that's a good habit to cultivate on principle. What's this about?"

"Sunbae wants to figure out a better way to silo that gets the benefits of guiding without the problems that his backlash poses." He's sure Kim Hye-jin has figured at least some of it out by now. "But he's mortified to actually have the conversation himself and asked me to interface."

"Woo-young," he chokes out, sounding... well, mortified.

"Sunbae I have to say something and the truth is always the better strategy to actually solve problems."

"Oh! Oh okay. Yeah, that makes sense," she agrees, nodding. "So less possible interaction between us, while still being near each other?"

"Basically! And so that we can ground it, his—sunbae I'm not going to use that pretentious Western word—the best idea he's thought of that he could go with if we can't figure something out would be handcuffing and blindfolding and gagging him." Woo-young says that with a perfectly straight face.

The choking sound coming out of the speaker Hye-jin can only hear sure to the audio quality and esper hearing suggests that a certain someone else does not actually have a perfectly straight face.

Hye-jin snorts, and is obviously amused, but doesn't actually laugh. Her expression makes it clear that she thinks this is very silly, though.

"I don't think we're going to need to go that far to get him the privacy and safety he wants." Okay, that one is said with a perfectly straight face. "If nothing else, our compatibility is good enough that we might be able to guide each other through sufficiently thin walls, or - walls that don't quite go up to the ceiling? I suppose that doesn't help with the soundproofing, does it, hm, and my sincere promise to wear earbuds and listen to music or something is obviously not good enough... Is there paper in here?"

Yeah, sure, he can get her some.

Okay it's drawing time!! She's going to start scribbling possible wall-between-them variations that might work.

"So I think the full wall that's made of a material that doesn't block guiding is clearly best, especially if we can set up some kind of soundproofing on top of that, but I don't know if... anyone has researched that. Do we want a hatch in the wall for potential handholding, or is that better if it's not even a possibility?"

"That one's for you, sunbae."

"...it's probably a good idea."

"Hmmmm, then maybe two thin walls, with a little cushioned handholding area between them, and hatches on either side." Hye-jin starts drawing little stick figures and little lines between them. "If we set it up so we're facing opposite directions with one side to the wall, with both of our arms reaching into the designated handholding space, we maximize closeness of our bodies while keeping our respective heads away from each other. ... Does a reclining chair work okay for you? Nevermind, don't tell me, I shouldn't know anything about what's going on in your silo, I'm just thinking logistics..."

She has been nerdsniped by an interesting problem, and is now going to get kind of into it.

...where did they find her??? She's from the same damn planet sunbae's from. He, like, knows that esper compatibility is also a function of personality match but he didn't realise it'd be to this extent.

Explains how they can passively guide each other from such a large distance, though.

They found her in Japan! Wasn't he paying attention? She came from Japan.

Anyway, she is happily going to work out a detailed, multistep double silo system with multiple layers of fallback, depending on how much wall and space they can get away with putting between them, with hatches for handholding on both sides of the wall and a Designated Handholding Space in the middle. She has this power. No one is going to be able to stop her. Also, no one in this room seems to want to stop her, so.

"Oh, but this might take a while to get built, even with throwing lots of money at it to make it happen quickly," she muses. "Uh, does both of us on either side of a locked door work as a temporary solution until it gets sorted out? Blindfold, handcuffs, and gag optional?"

"Oh we can get it done by tomorrow," Woo-young says, casually. "Will need to consult sunbae on specifics—"

"I'm fine with whatever you've decided," he interjects.

"—I guess not! So it's a matter of finding people and we can definitely get people." C- and D-rank espers often don't go into dungeoning at all, unless they have very specific in-demand kinds of powers, and instead tend to do the superpowered version of mundane jobs, like construction work.

Nod! "Okay. Uh, for my side, a heated reclining chair, please. And a desk that can be pulled out. And other general hypothermia considerations. You're right handed, right, Tae-gun-sunbae? If so the handholding wall can be kept to our left for both of us, let us have our dominant hands free."

"He is," Woo-young says, nodding. "Write down a list of specific stuff you want? And I'll get someone to make a 3D blueprint off this," he taps the paper, "and share with the two of you so you can change anything you might want to."

"Mhm!" She happily gets to writing out a list. "Are you okay with doing the rest of our dungeons today with the current system, or the on-other-sides-of-a-locked door idea?" This is of course to Tae-gun.

"...locked door, I think," he says after a second.
