Under the moonlight, the Grim Reaper waved his sickle, ready to harvest the man's life. The man asked, "How can I not die?" Death said: "Find a girl, as long as she is willing to give up her life and dedicate her soul to you, you can live." The man asked: "How can a girl give up her life and give her soul to me?" Death said: "As long as you get her heart, let her fall in love with you." The man asked, "How can I win her heart?" Death smiled slightly and said, "It's very simple, exchange your heart for her heart."
