Gwen Stacy / Steve Rogers
After a couple of sips of her concoction, Gwen knew right away it was one of those drinks you just kind of had to hold your breath and swallow down and then cringe in the aftermath from the taste it left on your tongue. And that was fine. Those usually ended up reaping the best results. She wasn't worried about getting wasted. Her Spider Senses would hopefully tell her to slow down and even if that failed there was a shit ton of pizza she could eat to soak it up and if that failed, well, it wasn't like she was driving or had to go fight the King Pin or anything.
Listen. If Mr. Rogers had come over to bust her for drinking or give her a lecture then she was going to revoke her 'cool' card from his possession. The thing about Steve was that she really liked the guy. He was Captain America, for spidey's sake. But he was also important to Tony, and they were all kinda living together like a family so she had a lot of heart for Steve Rogers. It was bumpy at first. Like when your parent got a new boyfriend and you weren't really sure about it yet so you were kind of a dick to them but not really enough that it got you in trouble. That kind of thing.
But she'd talked to Tony about it without making it a huge deal but enough of a deal that he knew she was basically saying 'hey if this guy's a dick I'm taking him out at the knees' sort of thing and after that it'd been pretty great. So when Steve showed up and asked her to dance, Gwen chugged down the rest of her awful drink, set the cup down and took Steve's hand.
