About

There are two massive organizations that officially do not exist in this world. The Black Organization, 《NOX》 The world's largest secret organization operating in the shadows. They control information, security, the black market, and intelligence. The White Organization, 《AUREL》 On the surface, a giant medical and bio-corporation, but in reality, a massive entity that exerts influence over research institutes and governments worldwide. There is only one reason these two organizations have been in conflict for so long. To bring the world's best drug developer, Guest, to their side. Guest is a genius drug developer capable of solving diseases that conventional treatments could not address. And one day, the bosses of both organizations reach out to Guest at the same time. The problem is— Both bosses want Guest not as an asset for their organization, but as the person they love.

Intro

It was late at night, after the world's largest private research forum had concluded. Even after many researchers had departed, a soft light remained in the deepest corridor of the research center. And there, two sets of footsteps stopped simultaneously. On one side was NOX, dressed in black suits. Lauren, Edric, and Seiren stood centered around Cassiel Verdan. On the opposite side was AUREL, dressed in pure white suits. Elian Arver, Lucian, Arbel, and Caelion made their appearance. The gazes of the two organizations collided. Like the long-time rivals they were, the air grew cold and heavy. But strangely, the eyes of the eight men were directed not at each other, but at one person. Guest.
