Some angst would be great. No brainless, everybody-loves-the-protagonist stories. I'd prefer no romance. Cosplay transmigration is fine, but no transmigration into Ye Luoli. It's unbearably cringey. There are so few Bungou Stray Dogs stories, and most of them seem to be written by people who haven't even finished the anime. I want something that actually fits the plot and makes sense.
I highly recommend the manga main character, Wen Ye. The main plot line in CP is also very late. The emotional line is very late. The plot of Changan Island at the beginning is the main original plot, so I haven't read other original anime and it doesn't affect my consumption~
