Yes, finally, *finally* someone who also thought of Hannibal and Will while reading this. (๑•ㅂ•)و✧
I'd been looking at comments here for some time now, and I'd already thought I was really the only one who was totally reminded of Hannigram.
Literally everything you just said! I was like, could this be... murder husbands? Or maybe even along the line of some reverse conceptions, where Hannibal actually learns to "restrain" himself a bit, just for Will? (Which I personally prefer, such as emungere's masterpiece "Ladders") Pretty please? (人・ω・)
It's exactly as you said, Ah-in has obviously been through so much, with literally everyone in his life being a total asshole to him (and the poor guy doesn't even have at least a loyal pack of dogs who actually love him unconditionally ;), it would be sooo nice if killer guy could just become totally devoted to making him happy ┗(╥﹏╥)┛
We can dream, right? Realism is so overrated anyway ╮( ̄▽ ̄)╭

Not sure if I understand your question correctly... Hannigram (Hannibal/Will) is a popular ship for the Hannibal TV show... And there are quite a few excellent works on AO3, for one. (Like I mentioned, one of my personal favorites would be "Ladders" by emungere - it's quite long and really well written, imho :)
But if you mean a manga adaptation - there isn't anything like that, at least to my knowledge...
Me @ myself: he’s a killer with a possible unhealthy obsession and you cannot get attached to either of them—-
Also me, sobbing in a corner: I JUST— I JUST WANT THEM TO FALL IN LOVE Y’KNOW??? LIKE HANNIBAL AND WILL??? I JUST NEED THIS OK..... LET ME DREAM......
MY BBY HAS EXPERIENCED MANIPULATION AND ABUSE ALL HIS LIFE—
I JUST WANT CRAZY HOT KILLER MAN TO OBSESS OVER HIM AND KEEP HIM HAPPY— THATS ALL
KILLER HUSBANDS PLS— I JUST WANT KILLER HUSBANDS—
