This one while being more mature is a direct sequel to the first one, They're definitely two different stories.
The first one tackles the og king before Wolfgang takes the throne. If you want some back stories and initial dynamic between the two leads I'd recommend reading that first because not only is it good, the story is excellent with the ending wrapping it all up well.
I won't spoil anything tho have fun.

Do i have to read the non mature version of this to understand what’s going on in this one?
