She definitely said that I think you mixed novels.
Sentences was like
She said :
You made things right but only one thing, you made a mistake, you didn't trust me . If you told me I would listen you etc (a paragraph speech there) and she also said it was your only mistake . A mistake that make Ruina(? I am not sure that place's name) 's people free (it was kind of like this I couldn't remember exact sentences) she emphise that she would accompany him even it means he rebel against her family but also she emphise she know that not saying anything and killing her was safest bet for their city.At the end ,she appreciate his choices and don't blame him but still hurts that he didn't say.her
Oh I see where you mixed . Yes ,there was a part about that too. But it was about how she heard in prison that of he forgive her or say she is innocent and then send her to his hometown to live but that means claimed that many people won't believe him and they are ready to throw dirt to him . So she choose to die. And she apologized about "her lie". She kind of promised to go his hometown and live there but she choose to die.
You are right about this part but like I said it wasn't the part I mentioned.

I can’t be the only one who kinda dislikes the ML right? I don’t know I just feel like he could have done more to save her. I mean he knew about what was going on in her house and not once told her about what’s happening. I feel as though if she knew she would try to help the people more hence them seeing her in a better light. Yet he decided not to tell her and betrayed her trust and love. I don’t know I just think that he could have tried harder for her after fully knowing that she is a kind, and loving person.
