Basically, I looked at Sho's life in the movie and decided that he'll get a huge family and a bunch of wealth because it will make him realize how spoiled he is and it might be interesting as he tries to get rid of it the more he returns to his original self. I also sort of kind of gave him a life style closer to that of his actor's RL in some small forms since that guy is insane. And he pretty much created Sho as an echo of himself.

It's sorta a bit meta in a way idek
