[if there's someone who's skiving off class, it's usually not his problem, even if he is a kyokusei. but hey, the guy's in his year, and more than that, they went to school together before. So when he doesn't see him in classes even now, even though it's a whole new Academy, he gets curious.]
[so that (in part) is what leads him to wander out before the start of the History class that they share, beginning to wander quietly and basking in the quiet and the sunshine. Birthday would probably give him a pass if he said why he was looking for this guy, after all, and even without that, he's never paid much attention to human rules except for when he wants to.]
[smiling when he catches sight of the figure he's looking for, sleeping on a bench. it makes his mouth quirk-- that would make Captain laugh, hearing someone do that just like Fudou-san did. wandering over to him, pushing his boots aside not-too-gently and perching on the bench beside him unruffledly, even as the bell in the clock tower overheard chimes for class.]
Mou, Kai-kun. [tranquilly.] Are you not coming to History?
