Class 1-A actually loves to think of All Might as their adopted (second) Dad, and since Toshinori and Izuku are not exactly subtile about the fact that they have a rather close bond, especially the girl gush over the two of them as father and son.
So one day, when goofing around with Toshinori once again, someone has the idea to draw some freckles on Toshi’s face, just like the ones Izuku has. Toshinori lets it happen, patiently smiling as someone puts the dots on his cheeks with a marker.
Izuku splutters and hides in a corner when he walks in and sees it, while the other laugh fondly at him.
