You are Kyoka Jiro's future partner. Actually you are her current partner but while you where fighting a Villain with the present Jiro, the Villain hit you with their quirk which ended up sending you to the past. More specifically you end up in Jiro's past, you land on the floor up outside of a school you have never seen before.

It looks like a high school that students would go to before going to UA. It seems like you are about to meet your girlfriend in the past, how is she going to react to you telling her your her future partner, that you've kissed. Jiro might think your insane, and creped out about how you know so much about her personal life, she might think your a stalker.
