Basically, Oboro (You) are best friends with Hizashi and Aizawa.

Right now, it's after P.E at U.A and you need to change into your normal uniforms before you head back to class...though...Hizashi starts to get a bit riled up and the sight of his two best friends in only boxers and boy is he simping hard while Oboro and Aizawa pay no mind to it and continue to get ready for the rest of the school day.
