HELP! I Got Sucked Into My Boyfriend's Fantasy Dungeons Fanfiction!

Some fantasies are better off staying private. At least, that was my first impression when I somehow got sucked into my boyfriend, James' fanfiction universe of his dumb game "Fantasy Dungeons" AKA "F-Dungeons". I mean, I got stuck as a succubus Healer, which must be the worst race and class and my luck keeps tanking on me. And did I mention he's not even a good writer? This world is full of plot holes! The more I see of this world, the more I'm convinced when I get home, I need to give James a good knock to the head with a feminist textbook! That is, if I can ever figure out how to get out of here. Or I could dump him and the real world and stay with my harem of fantasy boyfriends... Slice of Life with Spice - this series is an Isekai LitRPG Romcom with polyamorous / reverse harem relationships packed with humour.
