She waits until his shoes are off before she takes him by the hand and starts tugging him along and down the stairs. But that's all he gets, because it's tour time.

"Okay, so there are sections that are still extremely sad, don't look at any of the guest rooms, and definitely don't go down past the main living level area, because while I will figure out a way to make hydroponics and a generator cute, I have not yet done it, and there's a lot of empty storage space..."

Her silo is not quite literally rated for surviving a nuclear apocalypse, being more outfitted for structurally withstanding intense heat and pressure, but it still has pretty damn good odds for managing it. This place is sturdy, and the layout was clearly very meticulously designed to maximize the available floor space in the extremely structurally sound domed shape. It's pretty cute about its efficient layout and decoration, though, and a lot of the furniture is built for comfort and function over surviving the homeowner's fiery wrath. Hye-jin seems to have found the curved walls of some of the outside rooms a fun challenge to work around, and there's a lot of room to grow and settle in over time.

And also she's really excited about showing him everything. Is he ready to hear about the air system of this house, and how it converts sea water to oxygen? Because she's sure going to tell him all about it, and the other slightly-too-prepared systems for keeping this place running even when completely cut off from the outside world.

Tae-gun's focus, perhaps predictably, is tactical: What escape avenues do they have if teleportation fails? How do they avoid being crushed by the ocean if something cracks? And so on. Not that he's overwhelming her with questions, but that's something he's constantly paying attention to.

...oh and, right, he needs to be positive and appreciative, he will also do this once he realises that that is a thing he should do.

So, the major non-teleportation escape route is a set of submersibles, a one way ascension chamber that will ascend to the surface and then float there with a distress beacon, and also a general distress beacon in the silo itself that can be activated in emergencies. The ocean crushing them is not really a concern, because while sea water is not the most corrosive and mean-spirited liquid known to man, it sure isn't nice to anything any human builds approximately ever. They are therefore under more than a hundred feet of rock beneath the ocean floor. More dangerous is actually the prospect of earthquakes; they are far enough west to be away from the closest fault line, but it's still a potential concern. This silo is as prepared as it can be for one, with Japan's best anti-earthquake technology stabilizing the dome that the silo is set in, but; that is the major risk to this location.

The closest civilization is the hydroelectric power plant that Hye-jin's mother quietly bankrolled, and it is both the thing that powers this silo, and the explanation to anyone investigating just what people were spending so much money on out here.

Hye-jin honestly is pretty fine with the tactics talk and doesn't seem particularly put out by having him want that first, and is if anything proud to tell him about it, but she absolutely lights up at the praise.

See it's very very easy to get him to do more of the praise thing because whenever she lights up be immediately wants to do more of the thing that caused it. 

She's so clever! This place is so cool! It'll be so useful! The tech is interesting! It looks pretty!

Actually, most of this was her mother's planning! Hye-jin herself has been minimally involved, and has mostly contributed financially and by having floorplan and interior decorating decisions. Her dad also called in some favors for the electrolysis system for the oxygen down here, he's a chemical engineer, and while he doesn't personally specialize in this in particular, he has some colleagues that were interested in it for submersibles and the support systems for water based dungeons that might crop up. She thinks her mom is planning to set up another company to quietly sell off the sea salt this place is making? Because that's a thing, they can technically just dump the salt back out into the ocean, but if you're already turning sea water into fresh water and oxygen (and hydrogen; this is what powers the generator) you might as well try to figure out something to do with the salt too, right? At least that's how her mother thinks.

Hye-jin is very fond of her parents, and. ... It's kind of clear that a lot of this is them, not her, and. They worked very hard to get their daughter a safe place to be.

...aww. Okay that's very sweet. He's happy Hye-jin has those people in her life.

He wants to meet them at some point actually that sounds slightly terrifying and also are they even at that point in their relationship and also he doesn't have parents of his own to introduce her to so it feels asymmetrical—

Not being a mind reader, she has no idea of his thoughts! But she's very happy to have them in her life, too.

Anyway, realistically speaking she will probably still be siloing mostly at Tae-gun's place, because not only is teleporting to this spot expensive, it doesn't properly have internet access. They have their commscreens and there is a relay for communication, but full internet access? Yeah no. Unfortunately not.

Still! They're set if there's a nuclear apocalypse or something!

...mrrrr. He doesn't like thinking about nuclear apocalypses. He can't do anything about those. Zombie apocalypses he can at least help with.

She giggles at this, and kisses him.

Tae-gun maybe should wait until Christmas proper, but—their schedules are unpredictable. Something could happen. He can't afford the risk. Arguably he should've done this earlier, but he spent too long dithering, so now it's Christmas Eve and if he waits until tomorrow and an emergency happens he is going to fling himself into the Han river.

He reviews the things he wants to say, makes sure his clothes are fine, checks that one text message for the hundredth time to make sure he's not fucking it up, then messages Hye-jin.

Hey.

Wow, Lee Tae-gun, that's an amazing start. Suave.

Do you have anything scheduled for today?

Wait, was that too obvious. Was it stupid. Why else would he ask—he needs to stop thinking. Also if she doesn't reply immediately he will in fact be consumed by the black hole of overthinking in his brain.

Nope! No dungeons today for me, at least as far as I know

Would it be okay for me to come over?

Such self-confidence. Much social skill. Wow.

Sure! I'm at my secret silo

You should just be able to teleport without needing approval now.

Alright. Here goes nothing.

He teleports.

He's wearing a suit. A different suit than the ones Hye-jin's seen him in before, dark blue and unbuttoned, with dark red inner linings. He's not wearing a tie, and his black shirt is unbuttoned to his collarbone. He's carrying a flowerpot with five dahlias in it, all of them different colours.

He's trying really hard not to fidget.

"Come in!" calls Hye-jin, who is in the middle of putting together... something? There are a lot of shelf like things strewn about the living area, and a set of instructions that she's meticulously following.

Then she spots him and pauses.

"...... uh?" she says, eloquently.

He had a thing to say!

He has completely forgotten what it was!

"Um." He offers her the flowers. "For you," he says, like a person who knows how to say words. That's who he is, Lee Tae-gun, a known words-sayer.

"Oh! Dahlias! Thank you, these will be lovely in, hm... I might end up splitting them up, the pink ones will look best in the second guest room, and I think I wanted some color in - um." She has self awareness, and also is aware that her partner is very dressed up and giving her (thankfully living! These flowers are not being sacrificed!) flowers and that this, perhaps, means that it is not interior decorating thoughts time.

"Yooooou did not come to hear my interior decorating thoughts, probably," she acknowledges, embarrassed.

"I, um." Fidget fidget. "I mean I love listening to you talk." Fidget. "But um. Do you. Maybe want to. Go out to have lunch with me." Fidget. "In a bit."

"I - yes? Why wouldn't I -? Oh in a date way! .... I still also mean yes just, um. ... I would like to change into nicer clothes first. If you mean, uh, literally. Right now."

"I-it doesn't need to be right, um, right now." Though it is, you know, almost lunch. So.
