The dungeon is in Korea, but as an esper with a pretty specialised power niche Haru is used to occasionally having to go international for these dungeons, and the fact that he already speaks Korean is definitely a bonus. The espers he's going to be working with are all in Quasar Guild, which is the largest one in Korea and which has just recently acquired a very powerful teleportation esper, one whose power can be stored in batteries Quasar also happened to already have in its possession, so they're covering the teleportation cost for Haru to get there.
He gives Haru a moment to rethink his decision to get wet but who's he kidding, here, he's pretty sure Haru's far too backlashed to give a fuck. "I wrote until I couldn't write anymore and then I decided to work out to get some of the stress out of my system and allow myself some time during which I could have no thoughts whatsoever."
"Well, you look substantially chilled out so at least something in that series of events must have worked."
"I think all of it did. I don't know if the thing I did is the same thing you do when you write in your notebooks but it was an interesting experience that I will continue to try doing once I no longer feel in danger of having my brain melt and leak out of my ears."
"I was thinking that perhaps we should instead take a bath. I feel like taking my time getting clean and, most importantly, getting you clean."
Swoop. He was in the middle of a back and shoulders workout so this twinges a bit but not in a bad way, and then up to the bathtub they can go, where Jaeha can do some unspeakable things to this boy while the water fills up and then some more things afterwards.
And once they're done with that Jaeha will sit behind Haru on their bed while he blowdries Haru's hair and occasionally kisses his neck and shoulders and cheeks and lips. Maybe Haru mostly doesn't need emotional support outside dealing with his backlash but Jaeha still wants to pamper him and take care of him in other ways.
He doesn't write much more during that time. Instead he messages some people from Quasar's directory of counsellors to set up a first meeting and then does what Haru suggested and starts reading the backscroll of Quasar's group chat, which leads him to notice and accept an invitation to the QQ group chat and read that backscroll.
He starts forming opinions about these people. He's starting to feel kin with Cricket, which can't be a good sign, so he'll need to review those opinions later with a kinder mindset, but it's a place to start.
The last dungeon of the day goes on for a while - it's been around the block a couple times - but it doesn't strain Haru's powers very hard, having a few very tough monsters rather than lots of them. He comes home for dinner. "Tadaima!"
"Okaeri!" He's almost done with dinner, which tonight is spicy tteokbokki with a cheese filling and fish sauce.
"Smells delicious. I will have to take on some cooking duties once I'm not sprinting any more, see how you like what I know how to make." He wants to be touching but he is not so backlashed that he can't allow Jaeha freedom of movement to complete the last steps of the meal.
"I look forward to it. And semi-relatedly, I realised we've been living together for almost a month now and I haven't shown you anything in Seoul, so I am of a mind to take you out on some dates soon."
"I have ideas of places to visit and things to do but not so much an order of operations or a set of dates in mind."
"If we start with a walk along the Han river," he says, nodding in the direction of the window that has a view to it, "I could show you some places and see which ones caught your fancy. There's the Yeuido Hangang Park and the National Museum, the National Cemetery is really pretty if you don't feel creeped out by the nearby graves, the Banpo Bridge Moonlight Rainbow Fountain will start having light shows soon, and there are lots of restaurants I know near all of these places. If we're lucky and the cherry blossoms start flowering soon we could also go watch them, I'd love to do that with you... There are other places in Seoul I could show you but I feel like this would be a nice start."
"That sounds lovely. I am not particularly creeped out by graves, graves had their chance to be creepy when we were assigned our ration of supernatural bullshit and they didn't participate at all."
"Well, they do participate occasionally in dungeons, but that's not really the same thing at all."
