[Aaand there go his fingers, digging into the bread a second time. Oops. If Susato had to find out about Hyde from a friend, does that mean Kazuma hadn't told her?]

Ah. Yes, I suppose Hyde may factor into his condition to some degree as well. [Kazuma had told him that Hyde is 'still a part of him', but he doesn't quite believe that. What he does believe is that memories of Hyde's less scrupulous actions increase the intensity of Kazuma's nightmares.]

Is that... not something that Kazuma shared with you on his own accord?
