I Married My Ex's Older Sister

"On the eve of our wedding, Evelyn Gates fell to her death. Everyone believed that, since I had always been devoted to her, I would take my own life to follow her. However, I didn’t shed a single tear. Three years later, I saw her again. Not only was she alive, but she had no memory of the past. “So you’re my ex-fiancé? After all these years, why do you look so broke and shabby now? For old time’s sake, I’ll give you one day a week to wait on me.” I didn’t even bother to look her in the eye. Evelyn had no idea that, on the very night she fell, I received a video recording. She didn’t know that, during the three years she spent pretending to have amnesia while traveling the world with Cole Anderson, I had gotten married. My bride was her older sister."
