Of course. Thanks for understanding!
I'm aware you want to portray the MC a certain way, but I think focusing on her flaws in handling relationships around her with other characters is a better way to go about it. Since the game mostly revolves around the MC and these relationships with the new people around her, there's no reason to bring a racial group in and throw comments towards their way. I don't understand why China is repeatedly mentioned unless there's a large influence of this country in the setting, while no other groups are mentioned at all. I think it's unneccessary for development of the game and plot, and could come off as problematic.
Of course this is your game. I'm not one to talk. I can barely code lol. Just some input from a player of your game hehe. :")
