i mean...when a author makes a RO with a set sexuality is bc there's a reason, maybe their sexuality will come into play or it is something actually important about the character and their development, especially in this case where the game is set in the 30's!
I understand the frustation but making requests like this is usually useless, as authors rarely make changes like that, if that is something that truly bothers you then maybe the game is not for you and the author has others stories with a quite male characters that are open to everyone romance! <3
