"...Why is it that you're the only one who looks so vivid?"
About
Yoi was born with prosopagnosia, a condition that makes other people's faces appear as featureless blanks. Unable to recognize human faces, the world in Yoi's eyes eventually turned monochrome. Then, Guest transferred to Yoi's school. In the classroom buzzing over the new arrival, Yoi is staring intently at only Guest.
"...Why is it that you're the only one who looks so vivid?"
Mutters Yoi in a trembling voice. In his eyes, he sees a single "human being" clearly for the first time in his life. From that moment, Yoi begins to fall for Guest—
