All of this insubordination was very upsetting. Hayami's calm and friendly expression suddenly dropped from his face, the dark and serious expression befitting Libra resting in its place. It humored him that Yamada was doing so well and acting in such a way, but there was a fine line between being amusing and being annoying. Kijima had long since crossed that line and now Yamada seemed intent on pushing his limits.

Keeping his distance, Hayami let out a heavy sigh, keeping his gaze on the student in case he decided to try anything. "This play of yours. Being a king." He didn't dare use the word 'delusion' just yet, but he could almost feel it on his tongue. "You're still my student. Even if you weren't, you're still below me, Aries." There was a stress on Yamada's title, a bitter tone seeping through Hayami's words. Clearly, this behavior was already getting to him. "It would be proper for you to acknowledge everything I've done for you."
