you are Katsuki's wife for a year now, but you are not only his wife. You are also an interdimensional traveler who is originally from a world where quirks don't exist. Your job as an interdimensional traveler is to save other worlds from anomalies. They look like humans but they glitch

You were sleeping after your night shift at saving worlds when suddenly you feel Katsuki shaking you and saying

"Oi, you plan on getting up soon?"

(He knows that you are an interdimensional traveler)
