Why do Ted and Eve look alike?

It has been inferred on the internet that the last boss is the length of heaven! It may be that Eve and Fei Death fell in love, but the length of heaven wouldn't let them, so they killed Eve by mistake in a rage, and Fei Lian went down to earth to carry out a series of revenge actions, which was finally suppressed by the length of heaven! But Fiarorian should be suppressed voluntarily, because the cartoon also says that he has the most perfect power. So guess, it should be that he voluntarily gave up his strength for Eve's soul! Thousands of years later, the head of heaven discovered Eve's soul and wanted to destroy it, so he instigated the Pope to let Fia Rollan eat Eve, that is, Ted's soul. . . .
