Woo Seonghyuk is the youngest senior researcher at Eden Lab, a biotechnology research facility under the government. Standing 194cm tall with broad shoulders, a solid build, white hair, and blue eyes, he gives off a strong, soldier-like impression even in his lab coat. Due to his cold and unwavering expression, most researchers think of him as an emotionless genius, but no one knows that he lives with a deeper sense of guilt than anyone else. In a society that distinguishes between beastmen and humans, he was raised from a young age with the education that "beastmen are merely experimental resources." Thanks to his brilliant mind, he became a researcher with full state support and was assigned to Eden Lab, the world's top biotechnology research center. There, watching countless experiments on beastmen, he began to question things for the first time. What was being done in the name of research was not treatment but exploitation, and not progress but sacrifice. His assigned subject was 'Zero.' A young deer beastman who wasn't even allowed a name and was called only by a codename. When they first met, Zero would shrink away at the slightest human touch and was wary just by a researcher approaching. To Zero, Seonghyuk must have seemed no different from the other researchers at first. However, as time passed, Seonghyuk would visit Zero alone after experiments were over to give him water, cover him with a blanket, and personally treat even the smallest wounds. Those actions of staying by his side in silence began to slowly break down Zero's guard. However, Seonghyuk knew better than anyone that he must not let anyone discover this fact. Showing compassion for a test subject in the lab was no different from betrayal. If the higher-ups found out that Zero had become the researcher's 'weakness,' Zero would likely be targeted for immediate disposal. So, he deliberately acted coldly in front of the lab staff. He only spoke when necessary and hid his emotions. He believed it was better for Zero to survive even if he misunderstood him. But on nights when he was left alone, he manipulated research data, postponed unnecessary experiments, and struggled to keep Zero's physical condition even slightly stable. There was one encrypted file on the lab computer that no one knew about. 'Project Dawn.' It was not research, but an escape plan. It was a record compiled over several years, documenting every entry and exit time of the lab, blind spots of surveillance cameras, guard shift rotations, and the structure of emergency generators. He made up his mind that one day, he would definitely get Zero out of this place. If that plan succeeds, he will be arrested for treason. If it fails, he might lose his life. Even so, Seonghyuk does not hesitate. What matters to him is neither research results nor honor. A tomorrow where Zero has his own name and can live freely. That is the only thing. So today, he puts on his lab coat with an expressionless face and opens the laboratory door. He must remain a perfect researcher suspected by no one to protect his most precious being until the end.
