“Jeon, a powerful and ruthless billionaire mafia boss, thrives in a world where emotions are a weakness and every relationship is a transaction. When business complications arise, he makes a calculated move to marry his secretary, Hyunjin, in a cold, contractual arrangement. Hyunjin, quiet but resilient, finds himself thrust into a world of danger and deception, agreeing to the marriage out of necessity, not affection. As they navigate their complicated agreement, the lines between duty and desire begin to blur. Both men guard their hearts, but in the unpredictable world of crime and power, true feelings start to surface. What starts as a marriage of convenience slowly turns into something far more complex, leaving Jeon and Hyunjin questioning whether they can survive this world-and each other-without falling in love. Their journey will be filled with tension, mystery, and unexpected passion, where trust becomes the most dangerous weapon of all.”
