As the Dawn Breaks, to You

Amidst nothing but chaos and silence, the laboratory was a place where not a trace of warmth could be found. [BU-001 Experiment commencing.] The only thing Heesu wanted was... death. "I don't want to live anymore..." After enduring loveless abuse and countless unwanted experiments, the Sentinel Heesu had become so numb that he could no longer feel pain—or even emotions. Then one day, his compatible Guide, Seunghyeon, appears before him. "So it's you... my Guide." Unlike the other violent Guides, Seunghyeon treats Heesu with the utmost care, as though handling someone incredibly fragile. And through Seunghyeon's kindness, Heesu begins to experience emotions he has never felt before... "I'll stay by your side, so you can sleep without worrying, Yeomyeong." "...Heesu... Not 'Yeomyeong.' Heesu. Do Heesu." In Heesu's life, which had always been nothing but black and white, Seunghyeon's arrival gradually begins to fill it with color.
