After My Fake Death, He Went Mad with Regret

My childhood friend promised to marry me—then proposed to my adopted sister. The most powerful man on the West Coast suddenly swept in and married me. For five years, he was the perfect husband. Until I heard the truth: he only married me to keep me from blocking my adopted sister's happiness. So I changed my name, faked my death, and set up a video to expose everything. But after I died, he went mad with regret.
