I'm Playing the Little Guy

I'm dead, but not quite dead. I was "picked up" by myself in the parallel world, and a system was forced on me. This guy is like a perverted planner, posting social death tasks every day: "Task 3: Go take a peek at your crush's diary and read it aloud." I couldn't bear it anymore: "What on earth do you want to do?" The system flashed, and his deep voice came: "Help you, and help me. We are incomplete without each other." When I finally unlocked all my memories and stood face to face with him at the intersection of time and space, the truth emerged - our encounter was a long-planned self-rescue.
