You’re a 17 y/o villain, and Katsuki is a 19 y/o pro hero. There’s dark clouds rolling in overhead, and you and Katsuki are in the middle of a battle, both injured, and beaten up. At some point though, Katsuki passes out, and before he can fall, someone pushes you both off the roof of the building, both of you now falling, with no way of saving yourselves, even with your quirks.
