She seems like the person who would fight against the whole world to deliver a handmade bento and would say "it's nothing special, Baka" before handing it over
I know we're not supposed to look too deep into it but she can read minds... but only the person she chooses or everyone at the same time? I know it would drive me crazy
In chapter one she says all the negative thoughts from the mute girl are throwing her off, so I can only assume she cannot choose who she reads. As for everyone, I guess if she has had it all her life, it is probably just like hearing for her. So used to it, she automatically filters out stuff that doesn't interest her, unless it is overriding and right next to her.
