Explanation
I just saw some readers protesting that the protagonist did not marry Empress Sisi. Unfortunately, Haiyue had no way to compromise on this matter.
The tragic ending of Empress Sisi's love story had been fated from the very beginning. Precisely because he liked her, Haiyue could not bear to continue bringing her harm.
A beautiful woman who longed for a life of freedom was not suited to the Vienna Court. The beautiful fairy tale in the films stood in stark contrast to the misery of history.
Haiyue did not want to see her continue history's tragedy, spending her entire life languishing in sorrow within Vienna Court.
Being Empress did not merely mean glory; even more than that, it meant responsibility and duty. If one could not fulfill those responsibilities and obligations, then forcibly taking that position would doom them to tragedy—something no one could change.
Those who understood her might know what Empress Sisi said before her engagement—"How wonderful it would be if he were not the Emperor."
So everyone, please let her go. Letting her cast off her shackles and live freely would make her far happier than occupying that Empress's seat, where she would be bound forever!!
