The MC sadly is a real saint, so after being badly exiled and accused of doing bad stuff she is unable to really detest her old coutnry, even worse after a while the fake sends a assassin with a cursed blade to kill her as she discovered the MC got close to a royal she liked more than the tard prince, that she got close too because of his naivety, a knight on MC side winds against the assassin with her blessing, the curse is broken and reflected on the faker, that gets a massive scar/burn on 3/4 of her face, the idiots country gets ravaged by monsters raids with numerous commoners getting killed or mauled, some demon attacks the castle directly and kills the good knights that had to protect them, the nobles are taken in alive, that is very disgusting s they were mostly rotten.
After a while the MC gets in the conquered country and encoutneres the treacherous duo in the castle prison, they have a talk, the prince makes a dogeza and she totally forgives them and even heals the bitch, that I want to remember you got the scar when trying to KILL the MC, and as the curse bounced back on her EVERYBODY knew, but as I said she is a real saint and a idiot and forgives and frees them and they return to their position right after with the other nobles, it seems like the king plans to punish him but nothing short of public execution wouldn't make sense and if he was going to die there would be noreason to make him survive that long.
On another note, the fake is truly rotten to the core and there is a flashback with her being happy to her father, a good family man, suddendly dying because it makes her able to act on her own, I presume he was a from a noble family and renounced the title, so when he died she jumped back to them, she was truly happy of seeing her father dead.
There is a scene when she is healed where she realizes the MC is a real good person but every thing in her past doesn't just go away with "oh, she realized".
