the premise of this game is the dev wanna it to fulfill everyone's desires as much as possible. That's why we have many routes, from good wife, les, incest, to romantic with son's friend. And with aiden route, of course we will have rape route where sophia may become a whore. There is such nothing ruining the story, because the dev stir every tags in the game, and we the players decide how it's gonna go. Also, every path game contain many tags. In a nutshell, i think all of the routes are not mutually exclusive but yeah we have 4 focal route: dylan route(for incest), sam(for romantic), some female(idk who is the most important female in the game beside sophia, yet there must be one for lesbian) and aiden(for blackmail, rape)
