This is the silliest headline I've ever written and to make one thing clear, no I am not talking about the actual comics because that would make way too much sense.
Instead, I'm imploring you all to read this wonderful fan-comic:
The story revolves around Tony and Steve as the main characters but the other Avengers make frequent appearances too (with an absolutely wonderful Bruce Banner as the only one with a brain, with CAPSLOCK-Thor who shamelessly flirts with Tony (I ADORE THIS PAIRING, OKAY!!!), a sassy Natasha who actually laughs and makes fun of her teammates but is also very capable in fighting and a brilliantly funny Hawkeye).
I must admit I wasn't too fond of the art-style at first but it grew on me after a dozen panels and the small details (e.g. Steve's gestures, Tony's smiles and so forth) are great fun to spot.
The plot's main focus lies with Steve trying to cope with his love for Tony. For me, this is the biggest selling point already because of how the artist handles Steve as a person: he get angry, he gets hurt and disappointed, he is sexual (verily so... the comic is definitely NSFW! xP) and makes mistakes: a rare find in the non-comic-inspired-part of the fanfiction universe.
So if you have time to spare and are in desperate need of some Tony/Steve-shipping, there you go.=D
