[Yeah, good luck convincing anyone of that one, shun, especially the person standing right in front of you. In fact, Ren hums the most obnoxiously disbelieving sounding hum he's ever made at that.]

Is it not? Haven't we had to stop our lessons a couple times because you couldn't stay on your feet?

[That said, he's not interested in antagonizing Shun enough to make him really annoyed or even feel like kicking him out, so that's all he's going to say on that topic for now. Maybe reminding him that he has overworked himself to that point in the pass will make sure it's on his mind in the future. At least for a little while.]

By the way, what he is like, your new shinki?
