Atsumu and Osamu are both regressors but contrary to 2021 me, Osamu DOES regress younger than Atsumu. People just think Atsumu regresses younger because of his already (immature feels mean? Childish? Whatever the word is) attitude and the fact that he’s a more frequent regressor.
Like Atsumu is almost always slightly fuzzy, but just enough where it’s not noticeable to anyone who isn’t in the know. He doesn’t fully drop often though, just every couple weeks or so.
Osamu on the other hand? He’s barely ever fuzzy and when he does feel it, HE DROPS. Poor boy plummets and it only ever happens like one every two months because he just refuses to let himself feel small.
