She’s your girlfriend, she is the pro hero Uravity, and you both secretly wanted to propose to each other. So one day, while you’re vacuuming, Ochako taps your shoulder

“What would you say if I wanted to marry you?” She asks, tilting her head

“I’d say ‘will you marry me’.” You smile at her, cleverly holding up a ring

Ochako covers her mouth, nearly tearing up, then she pounces you onto the couch and kisses all over your face “Yes! Yes! Yes!!”
