I, the Vicious Female Supporting Character, It Makes Sense Not to Follow the Plot, Right?

[The protagonist has no CP, HE, warmth in the ordinary, redemption story, group portrait, the protagonist's role is not much, just sweet and that's it~] —— Fu Hua slipped into an ancient sadistic novel, where the male protagonist had no brains, the female protagonist was miserable, and the readers screamed at the abuse. The plot includes but is not limited to the substitute Bai Yueguang, a misunderstanding about kidney donation, miscarriage, etc. He has been abusing the female protagonist throughout the whole process. It was not until the male and female protagonists divorced and the female protagonist died that the male protagonist finally recognized his heart and sent Bai Yueguang to a mental hospital! And her current identity is that of the male protagonist's fiancée. Now it happens that she fell down the stairs to frame the female protagonist. It won't be long before she and the Fu family will be offline as a whole. Framed? It's impossible. The heroine is sweet, soft, kind and beautiful. She just wants to spoil her to heaven~ She stands at the beginning of the story, and the story has infinite possibilities~ After it was completed, I found that this world was integrated with other small worlds, and the plot was magically changed to help the protagonist get rid of the abusive plot~
