Two things for the start. First, I haven't watched any of the previews installements and I didn't read the book. So, I don't compare any version. Second, I dropped the drama. I watched about the half.
I cannot understand why someone likes this drama or how they can finish it. And it was really hyped, even in Netflix. I understand the cliches of the concept and the story (the school theme, rich male/poor female, bad mother-in-law etc) but it has the worst and the most tiring plot and use ever. There are a lot of similar dramas with the same themes, Heirs is the best, that use them in an interesting way. Bad female lead but I think it is the role bad written not the actress and she had chemistry with no one. Every episode with a new incident with no logic, only for the dramatics and more episodes.

Second, the whole bully turned lover is a problematic trope. It is a really dangerous standard that we teach the men that can do anything to women and not be punished and women to not speak up because "boys are boys" . It is wrong. Also, in general this thing is full of misogyny and patriarchal views from the evil mother to the belief that the girl has to be perfect and cooks "because it is a woman job".

But there was two things I apreciated. The acting of the F4 actors, especially Dylan Wang and Darren Chen.
