Keigo certainly played his part of celebrity-hero well. And no, he wasn't All Might or anything, but anybody in Japan knew who he was.
Kids wanted to be him. Elderly women kissed him on the cheek. Every teenage girl he'd ever walked by squealed. So yeah, he was pretty aware of his fame.
Which is why this was... new.
He'd been strolling the sidewalk in a quieter neighborhood after some later night flying, when you'd come running up to him. Oh jeez, I'd be fine with an autograph, but I hope they don't want a photo...
And then all you said was, "you dropped a receipt."
He stared at you for a moment, waiting for the blushing, the inevitable ask, but you just looked a little puzzled he wasn't responding.
"Thanks," he said slowly, reaching to take it. He couldn't remember the last time he'd had a street interaction as... plain as this. Maybe never.
You were just about to leave, too, because that's what normal people do, but-
"Hey, wait. What's... are you busy right now?" he attempted softly, taking a little step forward.
