This was such a nice chapter. The pacing is getting slower, if I'm not mistaken, it should be pretty much the same as the novel at this point. I totally forgot that scene where Arnold thanks her, that manga cap was beautiful. It seems that the Arnold's social persona is peeling off, we got to see more scenes of his trademark poker face and I just can't wait for more of his trademark "..." a.k.a. his general response to everything.
If I'm not mistaken, some of the Rishe's inner analysis of Arnold were cut off but we will probably get back to that when the story starts getting serious.
