Originally, I lived a happy life with my partner, but one day, I died and was reborn. I thought that after I was reborn, I should continue to find my partner like in my previous life. But I never expected that there was a stupid system that asked me to capture me, so I was not only reborn, but also traveled through time and became my love rival (I thought). I wanted to catch up with my original self in my love rival's body.
Concept: The love rival you think may not be yours
