Beyond memories, friend or faux (though it's still hasn't yet reach the core angst part in the novel), the edge of ambiguity (thou kinda annoying)
The one story I almost couldn't get through: http://itou_san_kuraka_sui
If you want a good cry then read 10years I loved you the most
I mean like really really sad stuff, I don't mind the genre or whether its BL or not, I just want really toxic relationships or something where you really feel for the lead like even when they're being treated wrong they still remain because they can't do anything but love the other person. A good example of something that I like would be into the rose garden's first season though its not nearly as angsty now.
Thanks!
