You were Tomura's therapist for a while since someone who liked to be called AFO kept insisting on that one.

Tomura sat down on a couch in the room and looked up at the ceiling

"Don't try to trick me into saying something again. It won't work"

He said for a few sessions he was like this and was refusing to open up about his past and what's on his mind that bothers him yet at least with you he was talking while with the other therapist he didn't even bother to open his mouth.
