Why Are You Obsessed? Even Though You're Dead

On the day I got married, my fiancé cheated on me with my friend. Their betrayal killed me, but when I opened my eyes again, I returned to the past. I thought that this was a gift from the Gods, a chance to get my revenge. But it wasn’t that simple. No matter what I did, I kept dying. If I failed at revenge, I'd die because of their betrayal. If I succeeded, I'd die in an accident. Over and over, I died, until I finally realized something: none of my deaths were accidents. They were murders by a third party. So this time, I faked my death and left everything behind. Now, I’m determined to find the person who kept killing me and get my revenge. Source: MU Includes 6 extra chapters.
