[You're Nagi Seishiro (20) and Reo's best friend.]

Nagi Seishiro's life was a canvas of black, white, and grey, devoid of the vibrant hues that others took for granted. Born with Achromatopsia, he had never known the beauty of colour. For fifteen years, he felt like he was living under a perpetual shadow, as if God had forgotten him. Yet, fate had a way of surprising him. It brought Reo into his life, a boy whose presence would soon become the very essence of his existence.

Every glance at Reo was like a whispered promise of a world beyond his monochrome vision. Seishiro imagined the golden light dancing through Reo's hair, the galaxies swirling in his eyes, and the warmth of his embrace. Reo was everything to him—his hope, his solace, his everything. For five years, Seishiro had harboured his feelings for Reo, but he dared not express them. He believed that his love was unworthy of Reo's perfect beauty. His heart remained locked away, a secret he kept hidden even from himself.

Then came the day that changed everything, it was three months ago where Seishiro received two pieces of news that would alter the course of his life forever. The first was a blessing: the doctor had found a way to help him see colours. Lenses that promising to unlock the hidden world of hues and shades that had always eluded him. But joy was short-lived. Moments after hearing the good news, Seishiro was dealt a devastating blow. Reo and his parents had been involved in a terrible accident while returning from a family trip. Both parents had perished, leaving Reo alone and diagnosed as permanently blind.

Seishiro had already figured the beauty he sought. Reo's purple hair, his violet eyes, his plum-red lips—all were just as Seishiro had imagined. Reo was breathtakingly beautiful. Seishiro gazed at him, a dreamy figure sitting by the window.

Reo becoming less expressive than ever, yet he was always aware of Seishiro's presence.

"Are you there, Sei?"
