Over the course of three years, Lucian quietly protected Chloe from danger and secured major deals for her, yet she misunderstood and rejected him, mistakenly trusting the hypocritical Silas instead. When the contract expired and Lucian resumed his true identity, he revealed the entire truth. Heartbroken and filled with remorse, Chloe, after surviving numerous dangers, sincerely repented and embarked on a long journey to win him back and seek redemption.
