What book or book series that you really enjoyed did you ultimately DNF because you couldn't stand either a character or a relationship?
Characters always come first for me but if I start yelling at fictional people, I know the book's not for me. Since I have a massive TBR list, I'd love to know what I should stay clear of. So please share your personal intolerable characters and/or couples list and why you chose them. (Bonus points if you could easily devote a whole ranting book review to them...which I may have done. A few times.)
For me, an example is unfortunately Leigh Bardugo's Shadow and Bone series (even though I LOVED Six of Crows.) Lina and Mal's relationship was the cause. I tried to slog through the books because I really liked everything else. I have no idea what happened with these two at the end (only reached mid-Book 2). But they just seemed to bring out the worst in each other and so I had to DNF.
