It wasn't like Ochaco to just not talk to you, is it? You two were best friends in middle, but ever since she started talking to Midoriya, she started ignoring you like you were never her friend, and it was a bit painful considering you were her first friend she ever made

Even Mina, Tsuyu, and Tenya saw this, and didn't like Ochaco's new attitude. It was like she changed.
