I don’t think there’s any thoughts of revenge. If you read the summary it says that rather than revenge she will spend her time with something else. Like romance.
The assumptions here are somewhat sensible. When Beatrice and Noah first met. He said something about unsettling. Something he didn’t like coming from her. When I was reading the raw, I was convinced that he felt something romantic from her, but instead got a bad a feeling when I read it translated.
