Let's think about what you mean by "stay"?
Do you mean that the MC will have a romance with one of the girls or with all of them?
If that's what you mean, then you won't be able to "stay" with any of them, because this game has nothing to do with romance, love, passion, none of that.
Now if what you mean by "stay" means that the MC will be able to fuck one or all of the girls, then the answer is yes, the MC will be able to fuck all of the girls throughout the game.
This game is all about sex and nothing about romance. There are no feelings involved other than a hard-on on the MC's part.
