(Actors Au) you and Kirishima are famous actors and youre both acting on set. You two are dating. As the script says you two are supposed to have an argument. You two start to improvise, not going with the skript making the director amazed. But what he dosent know, about the improvisation, is that you two arent acting. Leaving the rest of the cast (Izuku, Katsuki, Shoto, Mina etc) either worried, confused or fasinated at your "acting"
