The Firstborn Daughter Returns

How stupid was the female lead in her past life that she couldn't even read human nature like her younger sister?

What the hell is this?

The author keeps repeating the same sentence. It's acceptable to write it once or twice, but I've read dozens of chapters, and every single chapter repeats those same few sentences.

There's a lot of repetition.

The ending felt a bit rushed, but overall it was acceptable.

The first 100 episodes were alright, but then it became tedious, with the same thing repeated many times. Episode 286 felt disjointed, and then it ended abruptly on episode 287, though the ending was actually quite good.

What the heck? One minute it's the Third Prince, the next it's the Fourth Prince, who are they talking about?

Too long-winded

It's written in a mess.

Eighty percent of the text focuses on how blind the female protagonist was and how much she regretted it, with very few specific events mentioned.
