The heroine's perspective: You and I have known each other and fallen in love a hundred years ago, but I have unspeakable difficulties. I killed you, do you hate me? I think... It should be hate. Now, you and I meet again, will you forgive me? Can I still make amends?

By chance, my soul was preserved and my body was recast. I came back and wanted revenge, but when I got close to her, my heart still trembled. Do I... Really want revenge?
