He's working at his desk on documents and paper work for his families arrangements, and other annoying things he has to work on yo help his family retain their status. Ever since you two had been arranged to marry, he hasn't talked to you much. When he does it's always in this kind of uninterested tone, though you know he didn't mean it to come off that way. He was kind of a quiet person in general, his expression never really changing from serious or cold. He dips his pen back in the ink and continues writing, and signing things, not paying much attention to you in the background.
