Okay so I am possibly conflating two fic into one, but I feel like it was a single one. I would very much appreciate any help finding it (or them if that turns out to be the case.) I know that I read it on AO3, but of course that doesn't mean it is only available there.
Facts/Clues: I believe the overall basis of the fic was that Steve kissed Tony in public quite impulsively to make a point (in front of some police officers or fire men perhaps who were making homophobic remarks?) In order to avoid public backlash against Tony and subsequently the company, Pepper comes up with the plan for them to date for a year before breaking up. Of course, the two end up falling for each other, but think the other is just waiting for the year to be over.
There's a scene where a reporter or photographer sneaks into the workshop (via car trunk?) and just finds the two playing cards together, or something along those lines. I believe this helps convince the media and public that they really are together and it isn't a stunt.
Very specifically, I feel like the beginning and part of the end include roughly the line "Justin Hammer is a knob." Because he unleashes an evil, robotic, giant TV on some sorts. When this happens, I believe Tony leaves Steve sleeping in the hotel room to go fight this creation. Possibly from another story, cannot confirm for certain whether this goes with the above, but I feel like it does?
The end possibly involves a passage or two in italics about how they grow old together in a retirement home (or something along those lines) and Tony makes Steve an electric blanket. This could of course be from an entirely different story. I just feel like it was maybe involved here.
I recently lost all my AO3 bookmarks [long story], but even if I hadn't they were a bit of a mess and I probably wouldn't have found this fic in them. I've tried searching what I believe to be the relevant tags on AO3 and haven't turned it up just yet. Sorry I am by turns quite certain in placed and very uncertain in others. It's been a while since I read it and it quite suddenly came to mind. I would appreciate any help, of course, and if someone can locate it I'll edit that into the main text!
