Therdeo didn't deny any of her accusations. She may as well be telling the truth about all the mistreatment. And if she was, she has all the right to get angry.
Rather than didn’t deny, he barely got a word to speak before she kept cutting him off lmao. Wdym, you think not being able to speak up equals automatic truth? She was already wrong about her own assumptions of what the FL is going through
She only asked is Peri was already in the know, since she looked so innocent. And Therdeo could have spoken up, I think, if he wanted. Or at least that's the impresion I get from how the panels are drawn. But he looked too shocked at her accusations for that.
Again, that's only how I perceived the chapter, doesn't mean I cannot be wrong as well. But the fact that it was her saying that she counldn't forget him, and that Therdeo had her under surveillance against her wishes makes me suspect something else happened behind the scenes.
Who does she think she is? Coming out of nowhere and getting all angry
