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.
"Well, 'shinrigakusha' is kind of a mouthful and not a normal suffix. I could have told you about the homework, it got on my nerves. What's your homework?"
"I'd just have used her full name," he says, because he doesn't want to answer the question.
He's going to anyway. "My homework is... difficult. Or, well, part of it is. Another part is just filling out some questionnaires."
"...okay, you don't have to tell me if you don't wanna. Uhhhh I rescued an American today and she tried to tip me, so that was funny."
He snorts and covers his eyes. "I do wanna, I kinda gotta because it's about you, it's just embarrassing and I'm putting it off."
"I think we have conclusively determined by now that my feelings about my image are only very tenuously connected to reality."
"I do sometimes tease and I can in fact not do it about whatever this is, if it helps! But yeah I didn't expect it to make a huge difference."
"She gave me a pretty good suggestion which is that I should text you about it rather than say it out loud, but you being right next to me ruins it. Unfortunately you just came back from a dungeon so I'm not about to let you go, at least not without pounding whatever sense you've got missing back into you."
Jaeha kisses him. "I hope I can distract you from the suspense. Permission to carry you to the bedroom?"
It's somewhat harder but still not objectively hard to get Jaeha to at least not be constantly thinking about it. Spending time with his ✨boyfriend✨ has the tendency to occupy all of his thoughts.
And once the sense is all duly injected into his poor senseless self Haru will kiss Jaeha and go off to do some work on his blog.
Oh there are kind of a lot of questions huh. They're all multiple choice though and kind of... Well, they sound like therapy questions, which, no, duh.
Is he going to successfully put it off long enough that Haru will be back, oh no, there'll be nothing he can do then—
He just needs to ask to go to a restaurant. That's all. Nothing more. Does he even need to text Haru that? Except he should also be paying attention to his feelings. And maybe tell Haru about those feelings, which honestly sounds terrible.
...he'll start writing this down, shall he.
He just needs to ask Haru to go to a restaurant with him. ...a fancy restaurant. One of the nice restaurants he knows, the kind that needs a reservation. The kind where you usually can't go in in jeans and T-shirt but Jaeha fortunately has more money than sense so he can bribe them to allow Haru in anyway.
(He could be using that money for charitable donations.)
(He might actually go completely insane if he starts thinking like that.)
(Note to future Jaeha: figure out how to deal with the fact that unless he donates everything he owns but the bare minimum necessary to survive he is not a good person.)
(He's not a good person yet, anyway, so it doesn't matter, he's going to spend money on a restaurant reservation.)
