Could these two novels be considered plagiarism?

There are two novels 1. In terms of character settings, the male protagonist is a prince, and the female protagonist is a rich young lady. The two male protagonists and the two female protagonists have similar personalities (the classic male protagonist is very strong and cold, and the female protagonist is very innocent and cute), but the specific focus is different. The female protagonist A focused on the fact that she was a rich young lady who had lost her memory, the female protagonist B focused on the fact that she was an adopted rich young lady, the female protagonist A focused on the entanglement between her and the male protagonist before she lost her memory, and the female protagonist B focused on the fact that her true identity was closely related to the male protagonist. 2. In terms of the plot, the two of them fell in love from the moment they met. The female leads of both works were very powerful and had very powerful masters and families. The female leads went to seek revenge on their enemies, while the male leads died trying to save the female leads. In the end, the male leads were revived (the overall framework was basically completely overlapping). However, the exact revenge plot, death plot, and resurrection plot were all different. 3. In terms of the style of the article, both of them were court articles. The writing style of the two was very similar, but there was not a single sentence that was exactly the same. However, some words had the same meaning, such as "I can't see anything anymore" and "nothing can enter my eyes anymore." 4. There are some similarities in some details. The two works have appeared in the plot of the mountain and the teahouse. The male and female protagonists have been out on patrol in civilian clothes. 5. The author of work B had read work A before writing, but he had no intention of plagiarizing it. He tried to avoid it when writing, but there were some framework routines (such as those mentioned in No. 2 High School) that could not be avoided. What was the definition of plagiarism? How similar was plagiarism? To judge a work for plagiarism, should one look at the plot, the character, the framework, or something else? Could fake things like the framework be judged as plagiarized? Please answer the question from a god who has the knowledge in this field! Because both works were used for commercial purposes, the relationship was more complicated…Thank you!
