The mc is so dumb I can't even

In my opinion, dumb is the wrong word. I would describe her behavior as helpless and alone. She was reborn into a completely unfamiliar world and into a body whose previous owner was fundamentally evil. o(>ω<)o
An established opinion of an entire society about a person is very difficult to change and i think the MC just wants to be herself.
Why is she so obsessed with her sister that sent her away and apparently has been telling the maid to poison her, please girl
