To clarify, her brother can read minds? Eyy I'm confuse help this poor soul ಥ‿ಥ

What?

I think no, She was talking out loud when she's nervous, that's why her brother can reply her 'thought'

OHHHH I THOUGHT SHE SAID THOSE IN HER HEAD. THANK YOUUU

I personally think he can 'cuz there were lots of hints that he can. And I don't buy his excuse of "she was talking out loud" while Charlotte doesn't even notice she is. I mean him saying "she's talking out loud" could hint in her mind always talking out loud of her thoughts .Well magic exists sooo and I'm pretty sure it not a speech bubble except the one where she said Richard-sama out of the bubble there are more hints but I'll leave it on what you thinkヾ(❀╹◡╹)ﾉ~

Oh
