I remember once reading a story with one. But he really needed to be locked up himself LOL.
There is a psychiatrist in zankoku na kami ga shihai suru, but this manga is very long, so this thread is not very expanded
well Kurose from ten count fits the bill right?!
Tho then again in this special case this can't really be called a professional relationship with for long.... And normally the probability of that still being okay would be pretty low, considering the influence and control the doctor's position has and the subjective view when the doc has an emotional influence himself. Just sayin' :D
So I'd also love to see stories where the lover would be assisting instead of carrying the whole burden. I'd only anticipate these things tearing a relationship apart and ruining both minds sooner or later.
If it wasn't fantasy, of course ^^
I wonder if there are any psychiatrists in mangaverse? Never seen any and a lot of characters need actual therapy.
