TS

For millions of years, Sebastian Michaelis and Claude Faustus have been locked in a secret, unbreakable relationship, hidden beneath their bitter rivalry in the mortal world. But when a catastrophic underworld anomaly hits London, Y/N—Satan’s personal administrative assistant and the second-most powerful entity in Hell—descends to take direct command of the mission. Instead of shattering their ancient bond, Y/N’s terrifying, primordial power completes it, turning their secret partnership into a synchronized, dark obsession. Bound by duty to their human masters but driven by absolute submission to Y/N, the two butler demons must navigate the crisis while wrestling with a possessive, suffocating devotion to their true Sovereign.
