Four years ago, Aiden—heir to the Ancient Blood Clan—signed a binding blood pact arranged by his family but fled to London to escape the ensuing "blood-bonding" wedding. Upon returning to Boston four years later, he was determined to annul the engagement and hired Emma, ​​a top attorney specializing in such contracts, to handle the case. Although they met in a professional capacity, neither realized they were the very partners bound by that pact; the bond they had shared in childhood lay buried beneath fragmented memories. Complications arose as an imposter named Chloe and the ambitious Julian repeatedly stirred up trouble, creating misunderstandings that kept the truth just out of reach. Yet, through their collaborative legal battles and shared crises, Aiden and Emma began to fall for one another. As the mysteries surrounding the blood pact and a childhood moonstone pendant unraveled, long-lost memories resurfaced. Breaking free from the shackles of a clan-imposed union, they refused to let the contract dictate their lives; instead, they chose to follow their hearts and define their own love and wedding on their own terms.
