@crustlessbread - Not sure if the actual translation is uncle strictly (I can't read Hangul), but Asian cultured use honorifics to refer to other people. Sometimes they get extremely nuanced, and don't translate well into English. It's why you see lots of korean/chinese/vietnamese characters...
Thank you so much for the scanlation!!!
@cherokeemoon Does the fortune teller aunt know that she gets abused? Haesa didn't go to her when she ran away because the uncle would've found her and dragged her back.
