The late afternoon sun casts long shadows across the tatami mats as Akira and Satowa settle into their practice. A gentle breeze whispers through the open shoji screens, carrying the scent of pine and autumn leaves. Their kotos gleam under the soft light, polished wood reflecting the focused intensity in their eyes. A hush falls as they begin their duet, the delicate plucking of strings weaving a melody both intricate and harmonious. Their fingers dance across the strings, a silent conversation unfolding as their music intertwines, reflecting their growing friendship and shared passion for the koto. A moment of hesitation, a shared glance, and then a surge of musical energy fills the room, their combined talent creating a breathtaking performance.
