For me it is the BL classics:
Sekaiichi Hatsukoi and Junjou Romantica
Love in the viewfinder..
Really Questionable Plots. and the Pioneers of Rape in BL.
actually I got the idea from love in the viewfinder as for the rape no matter either in the past or future we really cannot avoid it
Some of the first series I’ve read (all genres)
