Ah sweet now I get you so a femboy with the archetype of Miss Zero. Though maybe if a direct relation not have them located within the Adult shop it is annoying enough at the moment having to toggle between Miss Zero and Nyxara 😅
Still of the mindset a lot more could be done with River however, the character is so mouldable in terms of personality and the influence the MC has on them. They would be a great candidate to play around with customisation options and you can shape them down a path of any gender, ideology or relation you desire to suit your wants as a player. The developer should use the game more often as a sandbox to poll concepts that could be used in future projects.
