The setting for the story is... Dumb AF. Weirdly convoluted origin, but ok, that's to show she cares for her sister, tho the God is an asshole giving scam offers. But beside that, what's the worst is what she does after the engagement is broken and the story starts. She's not exiled, so what? Just ditch it all and use her broken skill of memorizing skills by seeing them (skill that's totally not making her a Mary Sue prime candidate) to earn living in other country. Even if there's something like Medieval Europe-style society, where peasants are part of the package that comes with the land, again, she has broken skills. Even staying as a maid would be good, that's a not bad job, even staying in the same country can pass, but damn it! At least leave the damn capital where everyone knows the Duke-villainess, go to countryside where no one knows you to avoid all the bothering people. Or if even not any of that, the Queen wants to put her as a maid to the new fiancé of her ex, and she just goes with that. Not like it wasn't showcased that the Prince's got a grudge against her for the past, right? Wait, it was, lol. And she does that without even trying to negotiate, saying how it's all her fault anyway when she was just going with Scammer God plan
