Jinsei Game to Shitai no Kanojo

There was a God who created the world to be in one place. God left the world he created to humanity, but one day when he looked into the human world, he noticed a girl. The girl jumped off her school rooftop to kill herself. God was very shocked by the behavior of the girl who just happened to catch his eye. "Is the world I created so uncomfortable?" God, who does not want to admit that the world he created was flawed, decided to rewind time and try to change the girl's fate. However, the girl died again and again. Yet still, God rewinds time -- over and over again.
