The chapter's simple, but did anybody else scope that Nazuna is getting this job so she won't need to suck Kou's blood? I'm 99% sure she hasn't gotten her blood from anywhere else since they started their relationship. That said, while it's part of a gag, she's also willing to abandon the endeavor entirely once Kabura tries to pry... but only for the time where it's unclear that she'll be able to get away with not explaining herself.
As an aside, regarding translation, a thought occurs between what I presume is the corporate scanlation and this one: on p.5-6, is Kabura fully aware of Nazuna's night job (like she is here), or is she vaguely aware (like she is in the corporate scanlation)? And while Kabura laments the loss of this opportunity, does Nazuna incorrectly
assume that she's worried (as she does in the corporate scanlation) or does she
question whether she is (as she does here)?
went from "bro I fuckin hate you get out of my sight"
"Disgusting vamp-shota... get out of my sight."
