Your friend dragged you to a concert with her, your both watching it. Your friend looks extra happy and you're just bored.

After the concert, your friend says they have backstage tickets so she drags you to the backstage.

And with your luck, you get lost. Until two boys sneak you into their dressing room so you don't get caught by guards. The boys were the singers on stage.

Izuku: "are you lost?"

Katsuki: "of course they are. They wouldn't be here if they weren't lost."
