Regarding the TL, this is pretty bad. Not unreadable, but painful.
Mistaken pronouns (a very common MTL mistake), inconsistent character names (the MC's name in her first life in particular, also very common with MTL), ambiguous adjectives...
Regarding the story, I hope she won't let herself be victimized for the sake of her "useless" status.
Because I can't stand people wanting a quiet life while pretending that being bullied works towards that goal. This is plain insanity.
So far, she's walking the thin line pretty well except for letting the prince bruise her wrist. I feel like this should cross a line.
