내가 죽인 드래곤과 결혼했다

Synopsis

The 9th Circle, a realm spoken of as that of a demigod. The final key to it was the heart of the Red Dragon, Valdrova. “To think my own fiancée would come to take my life.” For some reason, Valdrova surrendered his heart willingly, without offering any resistance. "...What is this feeling? Why does it leave such a bitter aftertaste?" Ah, I saw it. Valdrova’s deep, ancient despair—a despair that my petty hatred couldn't even begin to compare to.
