If you haven't already read this I would recommend 'Killing stalking' it is bl and has somewhat of a horror theme but the guy who is 'probably' the seme is pretty much the description of what oh want. I hope this helps :)
Killing stalking?
Thank you

Are there any manga where a character has borderline personality disorder? I love the psychological ones ^-^
