it's a name
It's a sound dogs make, but the way koreans hear it. In English it's woof woof, in Korean they say ang ang.
Ahhh I see. I assume that's connected to the story i.e. dogplay?
No, more like dom and sub. Master and slave/dog. Although the bottom is more often described as a cat
Is it literally just... Moaning? As in "Angh~♡, angh~♡"
