[Maybe his stance on things would be more similar if he hadn't been friends with Yuuki before she was taken back to the court. Now, he's one of the few she actually talks to about her mother and all the things here, so if his opinion on the queen isn't the highest... well, it's because of loyalty, too, but one to his friend.]
... I wouldn't put you in that position. You know Yuuki talks to me about things, right? So with her, I can speak freely. But if I said the same things to you, you'd be forced to report to Her Majesty, and- yeah. I'm not doing that to you, okay? [Because Yuuki isn't the only one he's showing loyalty to.]
