Even When I'm Dead

On the day of my wedding, I found out that my lover was cheating on me with my best friend. I died because of their betrayal, and when I opened my eyes again, I returned to the past. I thought this was a blessing from God, a chance to take revenge. But this return was neverending as I kept dying either from their betrayal or in an accident. After my repeated death, I realized that accidents did not cause all of my deaths but that I was being murdered. So this time, I faked my death and left everything behind to catch the murderer, who was killing me repeatedly and to take my revenge finally.
