Oh, mein Maximilian von Falkenstein!

In ancient times, lovers died when the heroine stabbed the hero with a sword to save him, but because of the curse of the first emperor, they were reborn in the second age, fell in love again, and died again when they were beaten to death to protect the hero. In the third age, the hero and heroine meet again and fall in love again. In this world, Ethan Vance saves Seraphina "Sera" Quinn at their first meeting, and Sera begins a fierce pursuit. Finally, the two fall in love, and until the end, Ethan Vance overdraws his physical strength to protect Sera, and eventually turns white overnight. Fortunately, there is a fruit of love, which saves Ethan Vance, and the family of three lives happily ever after.
