What about Steve smiling like a completely fool every time he looks at Tony? How would the rest of the team react, would they groan and roll their eyes because of that dork who is so in love with Tony?
I’m pretty sure this was meant as a prompt, but I’m just answering normally.
Anyways, Steve absolutely does this at the most random times. He just realizes how much he just LOVES Tony. Happens multiple times a week. It could be him arguing with someone at SHIELD or as simple as walking into a room. ANd he just has the BIGGEST heart eyes in the entire world. And everyone on the team teases him about it, as do the kids (well, except matt bc he’s a romantic and he’s lowkey been into the same girl since he was like, 10, and eventually marries her, so he believes in it and then is that person), but everyone finds it really endearing and it can honestly melt the most cynical of ice cold hearts.
