So about the exams, it specifically states she was enrolled in a school and she cleaned there instead of paying tuition. Even at that school she was taking classes advanced for her age. I do doubt a school like that would be teaching the same thing noble students would be learning, but that is where she is supposed to have learned those things.

This story is your typical cliché shoujo. The main character is a 7‑year‑old kid who somehow aces an exam meant for 15‑year‑olds. Which would be fine, if she wasn’t raised in an abusive household then tossed into an orphanage — like seriously, where’s all that knowledge supposed to come from? Anyway, from the start there’s alr 2 boys who are obv gonna get shipped to her, and a 3rd will prob show up later. Seems like no shoujo can survive without romanticizing every female‑male relationship. Platonic? Nah, cause then it’d be “illegal.” And it’s kinda bothering me how they show the girls running to the 2 boys — like, they’re freaking kids, not even teenagers yet. Why would they already be in love or interested in boys alr? ᵔࡇᵔ its disturbing at this point
