Frank/Gerard, I guess--it's a pairing I liked so much for a while, but I gradually got bored of it because some of the stories were very same-y, and then I became incredibly disillusioned by MCR as a whole and Frank and Gerard especially. RPS is so vulnerable in that way, it's harder to gloss over things that the "characters" do or to rewrite it, because things like Frank's abortion comments actually happened. So I can't even read most stories featuring them as a central pairing anymore, which is very unusual for me. (Note: this doesn't mean I think any of my friends who still like them/their band/fic about them are awful in any way. I'm in Marvel fandom, I can't cast stones.)
