A laboratory filled with nothing but commotion and silence, devoid of any warmth.
[BU-001: Commencing the experiment.]
All Heesu wants is… death.
*“I don’t want to live any longer…”*
One day, Seunghyun—the ideal Guide—appears before Heesu, a Sentinel who has become so numb from heartless, painful acts and unwanted experiments that he can no longer feel pain or emotion.
*“So it’s you, my Guide.”*
Unlike other violent Guides, Seunghyun treats Heesu with tenderness, as if he were a fragile being, and as he watches him, he begins to feel a strange emotion he has never experienced before...
*“I’ll always be by your side, so rest easy, Yeomyeong.”
“...Heesu... Not ‘Yeomyeong’—Heesu. Doh Heesu.”*
With Seunghyun’s arrival, colour begins to be added, bit by bit, to Heesu’s life, which had always been as black and white as a monochrome film.
