Unfortunately that's not how the dev pictures the game, I'm not even sure if there'll be any cosmetics customization when it comes to mc, but definitely it will be "him" fucking a range of female cast
Also, technically FMC is Yuna as she is the main objective in the game, she enables you to generate money and she has a relationship bar, so one could say the MC's world revolves around her, other chicks are just sidekicks
