Buddy "confused" is my default state of existence lol
Currently, there are no events in Season 2 that take your Season 1 choices into account, so there's no need for those choices to carry over.
When I finish the rewrite, the choices will be different, and they will affect the girls' side stories. It should all be within one game, too, so you shouldn't have to worry about loading previous saves.
But yes, for now, just download Season 2 and start a brand new save.
