The Person Is in the Wrong Place, and He Becomes the God of Order at the Beginning

God's law, a hard-working social beast, woke up and found that he had traveled through time. Good news: He traveled through time and became a god, Eunomia, the god of order and law, and the younger brother of Astraea, the goddess of justice. Bad news: The original owner ran away, forced his godhood on him, and slipped away to another world to have fun. Even worse news: He has no divine power and no divine power, so he has to go to the lower world to establish a family for his original owner. And the worst news - the original owner's sister, Astralia, seems to... Really love this brother. "I know you have always wanted to see the outside world. I won't stop you, but you have to promise me that no matter how far you go, you will remember to come back. My sister will wait for you." After reading this letter that did not belong to him, Jindailu fell silent. This god, what should he do?
