...Folks. Come on now.
She is twelve.
I dunno what you were like at 12, but "consistently smart and responsible" is not really a trait associated with that age. And even the kids that get the second and third bits down rarely manage the first bit: consistency.
She's an abused kid - a smart and plucky one yes, but still and abused kid - who was faced with the one person who had shown her kindness for her entire life up until... what, a couple months ago? And the only person who did so unprompted, I might add; yes the Salvatore's have taken her in and treated her well, but that's after she went to them. We've already been shown that she still internally believes they will cut ties with her when she turns 18.
I honestly have been consistently (ha) surprised at the quality of the storytelling here - not only is it refreshingly void of a lot of terrible tropes often seen in these kind of manwha (especially the more sexist "find yourself a man if you want to be happy, and if he's an asshole that's okay as long as he's hot. P.S. controlling you is sexy!" stuff), but very few of the characters feel like caricatures. The former maid, who I was worried would be made some stereotypically weak Judas figure, is actually shown as a far sadder, more tragic one. Possibly the only exception to this are the Sperados, and even with them, well...
We like to think of nobles as shining gallant knights. Heck, this story is an example. But if you look at a lot of European history, you had a lot of absolutely monstrous people in positions of aristocracy. The Sperados fit right in.
tl;dr This manwha has actually been really good at avoiding all the stereotypes people are accusing it of. People aren't perfect, and they don't look at real life with tv-tropes in mind - especially in a medieval world where tv-tropes doesn't exist. 😅
Also to the translators, great job. Keep doing what you're doing.
