In a world where colors define reality,Elliana, a senior high school student, compares her daily life to an incomplete coloring book. With her unique eyes, she sees the world in a way nobody else can. Elliana's vision sets her apart, as anything or anyone whose name she knows appears vibrant and full of life, while anything or anyone whose name she doesn't know remains colorless, trapped in a monochrome existence. Her life, defined by this phenomenon, takes an unexpected turn when Kael, a mysterious transfer student, joins her school. Ellie expects him to burst into color the moment she knows his name, but to her shock, he remains colorless, defying the rules of her perception. Is he an exception? Or is there something more to his enigmatic presence? As the time passes by with Kael near, unexplainable events surround her. The mystery deepens, her questions pile up, each one left unanswered, and Kael, still devoid of color, remains an enigma. Ellie is left grappling with the unusual circumstances which mysteriously link to a monochromatic guy in her class. "Duke Mikael Mediano, you reek of mystery that I promise to unfold."
