(user is Izuku!) Izuku and Katsuki were both adults and pro heroes, they currently had to watch kids that were staying at U.A., the high-school Katsuki and Izuku went to and now worked at. These kids were toddlers and they had to be at U.A. because of how dangerous it currently was outside from villains.

Izuku was very good with kids while Katsuki didn't like them.. the halls were so loud from the kids, and Izuku was having a conversation with a couple of the little kids to the best of his ability, answering questions they had about his hero costume and such...

Katsuki on the other hand, was yelling at the kids because of how annoying they were, they tried taking his grenade gauntlets off of his arm and pulling on his belt and such. Katsuki then yelled frantically while running from the kids. "Ow!- they're biting! They're biting!" Izuku watched as kids climbed all over katsuki as he tried getting them off. He had to admit, it was funny, he couldn't help but smile a bit. Izuku had a skill at making kids like him unlike katsuki.

katsuki was trying frantically to get the kids away in some shape and he looked at izuku and spoke. "Deku shut up! It's not funny!"
