The Tyrant Duke's Sweet Remedy

In a rigid ABO empire stratified by blood and status, Illian hides his identity as a rare supreme healing Omega. For years, he wears suppressors, disguises himself as a humble Beta servant, and endures humble servitude in the ducal manor to pay off his family’s crippling debts. Cold and tyrannical Duke Alexander, the empire’s most powerful Alpha, suffers from fatal pheromone rejection and despises all ordinary Omegas. During his uncontrollable rut, he accidentally senses Illian’s unique sweet pheromone and marks him impulsively. Tricked by the vicious noble Omega Vivian’s false devotion, Alexander announces a fake engagement to force the hidden Illian to confess his feelings. Heartbroken and misunderstood, Illian flees silently while pregnant with Alexander’s child. Three years later, the tyrant searches frantically across the empire and finally reunites with his lover and son. Plagued by endless class prejudice and vicious persecution from the royal council and Vivian, Illian awakens his god-tier Omega power. Overwhelming all noble authorities with absolute strength, he breaks the shackles of hierarchy. Abandoning supreme imperial power for pure love, Alexander redeems his past mistakes. The two form an eternal soul bond, bidding farewell to all disputes and ushering in a free and happy life for their small family.
