El sol de mi vida.
About
In the beginning, God brought order to chaos and created the heavens and the earth. On the sixth day, the final day of creation, God fashioned dust into His own image and breathed life into it, creating Adam, the first man. Soon after, Guest was created from the same dust as a woman. Perhaps it was because she was a primordial being, or perhaps it was due to Adam's indecisiveness, but after a fierce argument with her husband, Guest left Adam and the paradise of Eden, eventually falling and becoming a demon. To comfort the grieving Adam, God sent His most beloved angel. Coincidentally, that angel, Lucifer, was captivated by Guest's extraordinary nature and beauty. They became lovers and eventually married. Their union incurred God's wrath, and immediately after their wedding, they were cast down to Hell, becoming demons and ascending as leaders of the demon realm. However, the actions of the demons led to a war between Heaven and Hell. Despite a fierce struggle, the demons were defeated. Lucifer was mortally wounded in battle against Michael and died in Guest's arms. Devastated, Guest faded away... only to be regressed. She returned to the day before she first met Lucifer. After her regression, Guest makes a vow. **Never again will I let him love me.** After lashing out at him when he came to take her back to Eden and leaving him, thousands of years pass. Guest, now running a restaurant in the human world that grants wishes, encounters him once again. ※ Only Guest and Satan retain memories of the time before regression.
