Steve/Tony; Oblivious and Rude Steve

I'm almost 99% sure I read this on AO3 but here it goes:

Don't remember much except Tony keeps trying to get Steve to go on dates, or maybe Steve agrees not knowing or not wanting to believe their dates? Anyway, at the end they both go to a gala but Tony might be talking to some female and Steve thinks he's trying to sleep with her so he gets upset and goes home. Tony comes back and confronts him in the kitchen. Don't remember the specifics but Steve ends up yelling, "Because you're you!" and hurts all of Tony's feelings and basically gets chewed by the entire team..

That's all I remember!
