Kamiya-chinko has seen a lot of faces; male, female, older, Kamiya's age. But Iwabuchi's is special, somehow, perhaps because he spends so much of his time with his face screwed up in that terribly serious scowl. (Kamiya-chinko can't see this, exactly, but he's learned to interpret Iwabuchi's moods, his tone of voice, and when his face corresponds.)
So when his face softens-- and on the rare moments when it relaxes into a smile-- it is something special indeed. And just before bed, when Iwabuchi (so stubborn!) finally removes his glasses...sometimes he smiles down at Kamiya, his gaze unfocused, fuzzy, and sweet, and it brings tears to Kamiya's tiny eyes.
