Billionaire heir Ethan Miller tosses divorce papers across the marble table, arrogantly expecting his wife Serena Sterling to beg for another year of marriage. For three years, Serena quietly honored a secret contract marriage, tolerating Ethan's cold indifference and his family's condescending insults while concealing her identity as an internationally acclaimed forensic pathologist. The second the contract concludes, Serena signs without hesitation and steps directly into the state crime lab as chief medical examiner. Ethan is stunned by her abrupt departure, convinced she will come crawling back for his wealth. Instead, Ethan's younger brother is framed for a brutal high-profile murder, and the only person capable of uncovering the real serial killer is Serena herself. Forced to witness his ex-wife command police forces and solve impossible forensic puzzles, Ethan is consumed by suffocating regret. Can Ethan win back the brilliant woman he discarded, or has Serena moved on forever?
