The Supreme Demon Race was born as a demon, but he envied the human race's seven emotions and six desires, and envied their sincere feelings. In order to cover up his demonic aura, he worked hard to obtain a fire mirror stone that could seal all things. From then on, he became a mortal and experienced the path to immortality.
Until I met someone who engraved tenderness into my bones, and I lost my heart and soul for him from then on.
However, how could he have expected that from the very beginning, his ordinary heart was purchased with the lives of that man's entire family!
It's ridiculous that God gave him a chance to be a human being, but in the end he fell into the endless abyss again...
Concept: Is it really the original sin to be born a demon?
