I had been thinking the same thing as Yunseong, Hajin always drapes his arm over him and finds reason to touch Yunseong in an affectionate way. It’s the little details like that that show that these two are going above and beyond what is needed to retrieve the orb. And the fact that neither realize how extra they are is a funny plus. Like, it’s just to retrieve the orb: kisses during sex, Yunseong gets to be “cheeky” without suffering hajin’s wrath, calls hajin cute, the teasing, cheering each other up, etc.
