My Guardian Deity Is the God of Death

As her grandfather lay dying, little Rosa, who still didn't fully understand what death was, felt overwhelming grief. As she cried and cried, a gray man whose face she couldn't see appeared beside her and stroked her head. Then a miracle happened. "The old man is rallying!" When twelve-year-old Rosa passed the scene of a car accident and saw her friend lying in a pool of blood, she couldn't bear it and began to cry. Then her friend suddenly dusted himself off, got up, and called an ambulance. ...Rosa has a secret: there's always a man by her side whom only she can see. Every day, he asks her the same question: "Rosa, that person you hate. Should I make him die?" "No! Why don't you just renew my life card instead?" The heroine is a short-lived girl, and the God of Death keeps extending her life. Theme: 1
