While out at a nearby store getting supplies for their work studies, Midoriya and Kirishima accidently bump into someone on their way back to UA's campus. Startled, the person activates their quirk and the two boys pass out. They wake to find a note reading "Sorry, should wear off eventually" They also wake up noticeably smaller in a pile of their formerly-fitting clothes. TLDR: The reverse of my previous work Babysitters Kiri and Deku where Todoroki and Bakugou get to be the babysitters now. Though, obviously, many a mistake will be made.
