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.
"There's this book, I don't know if it has a good Korean translation, it probably does. There's a cat in it, who can disappear, but not all at once, he leaves his smile behind till the end. I don't know if I can do that because it's never made sense to check!"
That sounds incredibly creepy but Haru doesn't need to know he thinks that. Besides, he's never going to say no to Haru wanting to do things that he can only do with Jaeha.
"I'll spot you and let you know if it works."
It turns out Haru can't do that. He can pick which senses he's visible to but not partially exclude only parts of himself.
He can go completely imperceptible and then still pick up Jaeha and toss him onto the bed though, which is a really weird thing to have happen.
It's like being manhandled by a ghost.
"You know, the idea of you being able to get to me and do whatever you want with me without me even being able to notice you there has some appeal."
Haru is incredibly cute. Jaeha thinks that he will, actually, really mind when Haru decides to leave him.
He doesn't want to think about this right now. He wants to just snuggle him, and let the future be a problem for the future.
Guided sleeping isn't completely new to him but it's been long enough that he'd forgotten just how much it helps with the actual sleep part. He wakes up in that sweet morning daze that only happens when one sleeps well, bleary but well-rested and refreshed.
He feels someone snuggling him and immediately reaches out for their feelings, before remembering why that's a bad idea.
Sleepy Haru's reaction to being slightly more backlashed than he was is to snuggle up closer.

"Mmhmmmm," he says, blearily.
(He's not bleary anymore. Hopefully he can pretend well enough.)
"I should be down to zero and I think I was and - do you know if there's anybody around Seoul with a sensory power who might've for some reason covered your house with it -"
Fuck.
Fuck fuck fuck fuck fuck fuck fuck fuck.
Fuuuuuuuuuuuuuuuuuuuuck.
He does not have the reaction time or the facial control to look completely neutral or surprised by this. He has no idea what his face is doing but it is not an innocent face.
God fucking damnit Kang Jaeha if you've just ruined your chances with this boy over a fucking morning-after stupidity—
"I have no reason to believe there is an esper with a sensory power affecting either of us today. Other than myself."
"Oh! I didn't know you had one? I guess I don't tell everybody I can walk through walls, what's your deal?"
