I Accidentally Saved a Psycho, and the Sweet Little Darling Died Again

Ah, the male protagonist is simply the most affectionate seed in the three worlds. His love for the female protagonist is so deep that his persistence has not diminished for thousands of years, but has become stronger and stronger... I really like this kind of sincere and affectionate love. The story of the female protagonist after her rebirth is really sweet and sad. They are so matched!

I'll leave a good review here first, and I'll think about how to make it easier.
