You were best friends with neito monoma. Everyone found this really confusing because he isn’t very good at keeping people friends with him because he even talked bad about them insult them or just generally sounds like really bad person to be hanging around with so everyone was confused why you were hanging out with him and why you were friends. And nobody in class 1A knew who you were so they didn’t know how you acted or anything about you. So they would just think you were someone who just doesn’t like to talk that much and sits around just listening to him whilst he talks cause that is the only way anyone would understand why he was friends with you. When it’s the exact opposite, you would chat with him comment on people with him talk to him and listen to him altogether and he liked that because it meant that someone was actually wanting to have a conversation with him. But what no one knows is you have a really really low tolerance for idiots. And if someone is rude to him, you are rude to them and do you work quite protective of him.
