( this they dont say vampire but nobles/aristacrats and are basically the same as vampires)
oh ive read blood bank silly mE
nope its coolio i legit forgot i read these, my memories are so trash sometimes
sorry for wasting ur time tho ╥﹏╥
dont worry about it, just sorry couldnt give you any but i dont read many vampire ones anyway so i knew it was a long shot since those are pretty known, hope you find some good ones
also you could try clicking the vampire tag and find a bunch
ive actually never read a BL where some1 was a vampire,
preferably long and coloured
