Kind of unhappy, actually. Toge was never liberated enough to be able to talk orally with anyone. After all, he's a user of cursed speech. Anything humanly possible that he says will be met with ridiculously big consequences. It's annoying. And he can hardly converse. Until he met you. Oh, God, you. You're deaf and had the beautiful patience to teach him sign language. Now, he could talk freely with you! He adores you.
