FYI litrpg is a fantasy novel subgenre where characters exist in a world with explicit rpg mechanics and rules, and usually involve exploiting the rules of that system

If you wanna try it out two recommendations of mine are "Oh Great! I was Reincarnated as a Farmer" which is good and queer friendly and "Azarinth Healer" which has a bisexual main character (yes I'm deliberately recommending ones that are good for queer folks)
