Suggest me a book that will help my Dungeon Crawler Carl hangover

I am primarily a dark romance and romantasy reader with a sprinkle of litrpgs. I feel like I am chasing a high that I'll never get again after the DCC series. I read Operation Bounce House and liked it but I really want a book with the depth of DCC and the thirst of a dark romance.(The idea of a guy like Carl being an obsessive love interest has taken root) I am pretty busy so audiobooks are always a plus.
