God's Grace: Death System

Because of misunderstanding, she didn't cherish the man who always loved her from the very start. Huan Sulli just realized that her feelings she believes are hate but it is actually love. She regrets that she can't repay the love that man gave her as she died in a car accident. Her regret was so intense that the death gods took pity on her soul and sent her back to her world to correct all her misdeeds. In return for sending her back, she is required to repay it by completing missions on other worlds that are parallel to her own.
