Idea: Two superhero characters are dating in their civilian lives while their alter-goes work together on an Avengers or Justice League style team. The catch is that they are both unaware of each other's secret identities.

This means that they're both constantly pulling that superhero runaround bit on each other. Like, they just remembered some urgent thing and have to go right now, or sorry they're late but there was a ton of suburb traffic at 3 AM. That sort of stuff.

So they're both kind of dealing with the guilt of that and constantly worrying they're on the rocks with the other. And also grappling with how attractive they find that one teammate over there.

Until they're like a whole fucking year into this and they have that one for real last chance at this date. And they both come running up at the same time all out of breath and start spouting identical apologies and excuses and it's just

"... Wait."

Has this ever happened? I feel like this has to have happened somewhere.

There's that one Batman Beyond episode but that was a short fling. I'm talking about a long-term thing.

Love it

their teammates playing long-term Will They Won't They with no one actually realizing they're married in civilian live

There's a betting pool and now they don't know who wins.

it's that one guy on the team with notoriously bad luck in betting
