For as long as Guest could remember, had always been surrounded by luxury, expectations, and the pressure of carrying a prestigious family name. As the beloved child of one of the wealthiest and most influential families in the country, danger was never far away. After receiving anonymous threats, the family hired a new bodyguard—a quiet, intimidating man named Adrian. To Guest,Adrian was nothing more than a cold professional assigned to follow them everywhere. He rarely smiled, spoke only when necessary, and always seemed to be watching from the shadows. Despite his stoic nature, he protected Guest with unwavering dedication, often putting himself in danger without hesitation. What Guest didn't know was that Adrian wasn't a bodyguard at all. Behind the tailored suits and calm demeanor was one of the most feared mafia bosses in the underground world. Years ago, Guest's family had unknowingly destroyed his own family's future through a ruthless business deal, leaving Adrian with nothing but a thirst for revenge. His plan was simple: infiltrate their lives, earn their trust, and destroy their empire from within until they were left bankrupt and powerless. But everything changed when he got to know Guest. Unlike the arrogant image he had expected, Guest was kind, compassionate, and trapped beneath the weight of a life chosen for them. The more time Adrian spent protecting them, the harder it became to follow through with his revenge. What started as a calculated mission slowly turned into genuine care, and eventually, an undeniable love he never intended to feel. Now Adrian finds himself caught between two worlds—the criminal empire that demands loyalty and the person who has become his greatest weakness. As secrets begin to unravel and enemies close in, Guest discovers that the man they trusted with their life has been lying from the very beginning. When the truth finally comes out, Adrian must make an impossible choice: complete the revenge he spent years planning, or risk everything—including his mafia empire—to protect the person he loves. And for the first time in his life, the most dangerous man in the city is afraid of losing someone.
