Okay, I know it sounds crazy but hear me out man,
Basically, it'll be a love hate relationship. God, well, God's , Jesus, will be outgoing and happy most of the time. However, Satan will be shy and sensitive, he will also be abused by his father, the devil.
They'll meet at the heaven and hell border one day, Satan in tears because his father had just yelled at him ane called him a disappointment to their family. Jesus, being the softboi he is, will comfort Satan and they'll eventually become best friends, but what will happen if their parents find out?
