sadly is not how you want the game to be, but how the creators (Carrots and Vixel) want the game to be, maybe this game is not for you and it won't be for sure since the character that you show more interest into is female and she shows a lot of interest back to you, showing preferences on which sexuality you lean more is not how the game is getting developt.
and yes Carrots said that is going to be free.
