BL/GL where you didn't ship any couple?

BL / Josei / GL where...you didn't ship any couple? Is there any story that was supposed to involve romance where you actually didn't want any couple to get together? It happened to me with Back to school. I only liked the protagonist, meanwhile the good guy was a bit boring even if a good person, and the other guy...well...he was absolutely out of his mind and a rapist. I really didn't ship anything but I kept reading it to know the progression of the story.

Did it ever happen to you not to ship any couple for some reasons? Let me know, I'm curious. It's okay to answer things like Killing Stalking or Warehouse but it's also a bit obvious there ^^".
