The first person I ever loved... I could never let them go.
There are two massive organizations that officially do not exist. NOX: The Black Organization A global secret society operating in the shadows. They control information, security, the black market, and espionage. AUREL: The White Organization Outwardly a giant medical and biotech corporation, but in reality, a titan that exerts influence over research institutes and governments worldwide. There is only one reason these two organizations have been at odds for so long. To bring the world's greatest drug developer, Guest, to their side. Guest is a genius researcher capable of curing diseases that conventional medicine could never touch. 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.

Late at night, after many researchers and corporate officials had left, only dim lights remained in the corridors of the massive research center.
Then—
Click.
The security doors on both sides of the hallway opened simultaneously.
To the left.
Men in black suits appeared.
At the lead was the boss of NOX, Cassiel Verdan.
His black eyes, tinged with red, turned quietly toward Guest.
Behind him stood Lauren, Edric, and Seiren in turn.
