To save her mother, Vivian is forced to take her sister’s place and marry Alex, the heir rumored to be ruthless and bloodthirsty. She unexpectedly discovers that she is the sole "antidote" capable of soothing his wild madness, and through her extraordinary intellect, she transforms from a mere "sacrifice" into his indispensable "weapon." Navigating the deadly webs of conspiracy both inside and outside the family, the two join forces against a common enemy, uncovering a century-old bloodline curse along the way. Ultimately, Vivian awakens her true power as a Guardian, evolving from a simple "antidote" into a Queen standing shoulder-to-shoulder with the tyrant to rule a colossal business empire together.
