Akio Honjou is a high school student who possesses a unique musical talent: he can flawlessly recall any piece of music after hearing it just once. One day, while attempting to reproduce a particularly calming piano melody, he unexpectedly encounters Juri Makina—the girl whose cell phone had spontaneously played that same tune earlier in class. If art is the only way to truly understand the landscapes within others' inner worlds, can this specific melody help Akio begin to grasp the more intellectual and emotional dimensions of his captivating classmate, Juri?
