In exchange for having a relationship with Alpha Lyle, a dominant alpha who suffers from pheromone overload, Hae-jin, a recessive omega, receives support for his parents’ hospital care. However, due to the actions of the butler and the employees of Vermouth Mansion who despise Hae-jin, the contract between Hae-jin and Lyle was not properly fulfilled, and life in the mansion was miserable. Lyle, who was completely unaware of this fact, misunderstands Hae-jin’s behaviour and acts coldly toward him. But a sudden turn of events leads to the contract between two to an end. “I will end the contract.” “Okay. Get out of my mansion.” However, Lyle reappears in front of Hae-jin who left the mansion… “Why are you doing this to me?” “…It’s just that I don’t have anyone as convenient as you.”
