which some should i read first ? is there any difference in the stories ?

hello?

Hey
This version don’t have the first part
So go to non mature version and read first season there, it’s excellent and the best part of this manga for me (they are kids in first season)
Then you can read it here till the end, because it has the smut, and it’s great
Then this version is still not complete, when you finish here you can go there to the rest, the non mature version is already completed
