Here are the unscrupulous, the dysfonctional and sometimes utterly damned, souls of the BL genre.

Some run toward the lighter side with just a bit of moral ambiguity while others...even though they'd like to pretend to be romantic there's really nothing close to love in there, only cruel MLs and utter obssession (at least with the perpetrator). You've been warned.   
                                                               Requirements: an existing plot & decent writing

For those who would like published novels recommendations, here are my favs: ♥ "The Administration" serie by Manna Francis (available online) ♥ The "Beautiful Monsters" serie by Jex Lane ♥  "All for the Game" serie by Nora Sakavic ♥ "In the Company of Shadows" serie by Ais (online I think) ♥ Yakuza Pride by H.J.Brues.   Those are all genuinely dark & adult tales and are tbh, better than the novels listed here. Sadly, there's only so many times you can re-read a book.
