Oh, you made the poll, excellent! I'm gonna expand on our earlier discussion, and hopefully not contradict myself too much--for me it's something like:
What I can write: established relationship or similar that takes place in the background of gen content, giving me a context to write them together while not focusing centrally on the relationship itself
What I can't: attraction more even than pining? In the strictly sexual sense, or in the sense of limerence? No confidence that I can get it onto the page. Like, a few months back I saw a couple of young women on the subway who were adorably obviously together and obviously on a date, still unusual in this country, just wrapped in this sparkly aura of excitement and attraction and delight. I have no idea how I'd write that and make it work for the reader, although it would probably be a good exercise to try.
("And then Guardian happened": Shen Wei and Zhao Yunlan and company are SO MUCH that I'm actually more likely to take risks in writing them than in origfic; the emotions are so big and so there that it's easier to put them in writing.
