as suggested by the title, I am unfortunately VERY hard to please when it comes to bl manhwa however a huge big back which I just had to mention, not a picky eater AT ALL lol
As you can probably tell from my list my preferences are very much:
-psychological
-school life
-tragedy
-drama
-snusnu sometimes okay most times
-THE MCS ARE SIMILAR HEIGHTS AND BUILDS #NONE OF THAT TWINK X HUNK BUSINESS
-THE UKE IS SMART, INDEPENDENT AND A BAD BIYATCH
-F OMEGAVERSE UNLESS ITS ALPHA X ALPHA/ BETA OR THE OMEGA IS TALL GOOD LOOKING AND A BAD BIYATCH
-LOVE ME SOME NERD X JOCK/ POPULAR GUY
and the list goes on but you probably get the gist
