I understand that Maplestory is originally a Korean game, so everything in the game is defaulted to the heteronormative world. I also know that the game was developed and released in the 2000s when views on homosexuality was still negative and it remains unchanged in the game with gender restrictions because homophobia is still present in Korea.
However, it is 2022 and the world and our society have become more and more accepting of the LGBTQ+ community, so I think that GMS should reflect those new values and make changes to the game in support of the LGBTQ+ community. Changes such as making sex change available, making same-sex marriage an available option, and making couples items universal for all characters and not just restricted to one female and one male character.
