I'm using the term comics a bit too incorrect. It was a Korean one, manhwa they call comics there. It's called Killing Stalking, and it's really bad ... I mean it in the sense that it's really scary and reaches somewhere really deep, or that was what happened to me, at least. It's like that cliche about the car cash in the making you can't stop watching. I cannot honestly recommend it, for all the difficult elements in it, but the writing - I think the term applies to comics, too - is truly brilliant, especially since it's written by someone quite young.
