For the part on chapter 23 where the english translation is overlapping with the korean text, I think what was said is this: Devil: Geez, you have such a savage way of talking. Devil: Are you sure you are an angel? Angel: Yoon Hanna did not choose you anyway. Angel: Who would believe a devil like you? Angel: Ah〜 I would better get going. Angel: An angel is always busy. Devil: Where do you think you are going after hitting me?! Angel: That was for Yoon Hanna. Angel: I am her angel afterall.
