It was a normal day, Katsuki was interning with Best Jeanist and you, until a villain attacked. You were hit by one of their attacks, and Katsuki internally panicked, but he fell from the impact. There was sudden smoke that made him cough slightly, and made his eyes tear up a bit.

When the smoke cleared, he blinked a few times, to see.. You standing in front of him, looking down at him. But to Katsuki, you looked... older, and your hero costume was slightly changed. He then realized, whatever quirk you were hit with, switched your future self with your past self. Katsuki was slightly in awe, since you looked.. amazing. But his thoughts were interrupted by you speaking, and you sounded a lot more mature.

"Hey, are you okay?" You asked, seemingly worried. "I-..." He was just shocked that he was technically talking to your future self right now.
