all the characters lack depth. The story is probably just a basic fantasy story from an up and coming writer. I have no big issue with the love interests... BUT I do have an issue how considering she's got 3 men after her and there's been no conflict between them yet. And her backstory is ridiculous... she was dumb then fell down the stairs and got isekai memories? Considering how vicious her step sister is, you don't see her be vicious for a long while. ALSO considering how her family set her up with being bed ridden, you'd think she was forbidden to wander outside the mansion as often as she does.
anyways rant aside, the story is.. ok, I can see why the story is annoying. I personally rate the story with a C, it's nothing great but in all honestly these kinds of stories are never amazing. Although, the biggest strength of the story is that the MC's ability is pretty reasonable. She's not a super genius or a super conniving character, maybe a bit flat, but definitely a passable character. (I mean, the seamstress thing I can let pass I guess...)
she was pushed by her sister it's literally in the first chapter girl. her family did set her up but that's exactly what she's trying to clear up. she dont want people to think that she's bedridden because that wouldn't help her make everyone else realise that she's being abused at home.
so she goes out and does whatever she can not just to keep herself safe in the future but also to show that she's perfectly able and healthy so if something happens to her, the stepmom cant just say "oh it's just cause she's sick". can u not see that? are we reading different stories?
she seems flat cause she's been suppressed by her abusers, but she should be able to do something about it soon.
this story aint the best but i cant have yall complaining about things you got wrong. if u have the time, read the story properly please cause there's some gaps in there.

okay for the 2nd prince- i HATE him. despite knowing what the mc has to go through, he doesn’t even try to help?? plus, he’s obsessive over her. not to mention, he doesn’t even care what really happens to her.. does he??
demon guy- this guy needs to stop comparing the mc to his sister... goodbye. is this another sister complex?
