Something Sano does makes Saitou wonder briefly, but then he gets it.
After work, Saitou found Sano had taught himself how to leap up and perch on the top of the tallest vertical slat of the bridge near home, standing still high up like a long-leggèd crane or posturing ninja. He looked absurd, his gi and bandanna flapping in the evening breeze. But he jumped down, as Saitou began to cross, with a satisfied grin.
Of course Saitou must mock him for devoting so much time and effort to so silly and pointlessly difficult an undertaking, but even as he did, he realized the exercise was not only one of balance, which could benefit future combat, but it let Sano catch sight sooner, from that elevated situ, of Saitou’s figure coming t’ward him and the house they shared as of late through the growing dusk. It seemed meaningless, but the superficial hid unexpected depth.
Such too was Sano: an exterior often foolish and aimless screening intentions and a depth of character admirable and even delightful. This unexpected treasure in mind, somewhat to the bemusement of that same young man so complex and yet so simple, Saitou took his hand as they walked along, and said, “I love you, ahou.”
