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.

"It's not any more scandalous than the homosexuality, but I'm not sure if surrogacy is what's going to be happening, here, because Kang Jaehyuk would not want his daughter-in-not-exactly-law to be someone who doesn't know how the game works."
"If a surrogate decides to come after us for the infinite money my family has that would be a huge headache and, most importantly, terribly embarrassing. It's a tidy system when everyone knows how it works and what to expect and introducing outsiders to it upsets the tidiness. It might also be inherently embarrassing, to him, for all of the other rich old men's sons to be married to heiresses that secured alliances while his son got a surrogate to have his child overseas and is living in sin with a man."
"Hm. I think I don't like the one parent gets one kid, other parent gets other kid, system that your folks did, so while there might exist lesbian heiresses in the right class and age group it might be dicey to find one suitable for co-parenting with, that's a lot of filters."
"That is to be fair not necessary or the standard. I think Grandfather was just really paranoid. But yeah, that's why I never gave the possibility much thought, it just doesn't seem possible to satisfy Kang Jaehyuk's constraints."
"Do they have to be Korean, do they have to be themselves married, or could we be casting the net far enough for, like, Singaporean asexuals."
"I don't know. I think not being Korean could be a plus or a minus depending on where exactly they're from? Strengthening international relations is a plus and he might be willing to take a hit to the objective profitability of the arrangement if it helps secure alliances in, say, the US. But I'm just speculating, I haven't sat and had a conversation with Kang Jaehyuk in years."
"Well, I don't cultivate a network as a hobby but I have interviewed as many as several people, if that helps, albeit I don't know which large corporations have lesbian or ace heiresses."
