In Western mythology, there is heaven and hell. Angels live in heaven, which represents purity, while demons live in hell, which represents killing. Among them is the human world. People don't know that if angels and demons fall in love, they must tattoo each other's totems and hold a marriage contract ceremony. Oh, by the way, after the marriage contract is concluded, the two parties will also exchange identities. So basically no one would make this kind of contract even if they love each other deeply. However, if there is no marriage contract and one goes against God, it is not much better than the soul being annihilated and the body being shattered into pieces. Therefore, for hundreds of millions of years, angels and demons have no love but only hatred because of this harsh punishment. There is only one married couple. . . . . .
