Another theme might be the power of love to overcome or be influenced by historical events. If the novel is about love history, then it will surely touch on how love fares in different historical situations, whether it can survive or be transformed by things like wars, social changes etc. Also, the idea of redemption could be a theme. If the negligence has caused problems in the love story, perhaps there is a journey towards making things right or finding forgiveness within the historical framework of the story.
The theme of self - discovery could also be present. Characters might realize things about themselves through the experiences of love and the historical events around them. They could learn about their own values, desires, and how they fit into the historical and social norms while dealing with love that has been affected by willful negligence.
I'm not sure specifically which novel 'love history caused by willful negligence novel' is. But some general romantic historical novels like 'Pride and Prejudice' could be somewhat similar in terms of exploring relationships within a certain historical context.
The main theme might be about how wilful negligence can lead to the development of a love story. It could explore how certain inadvertent actions or lack of attention result in unexpected romantic connections.
I'm not sure as I haven't read the novel. But usually, there would be at least two main characters whose relationship is shaped by wilful negligence.

The novel might show how dreams were seen as powerful forces in different historical eras, whether it was for spiritual guidance, artistic inspiration, or predicting the future. And it could explore how that power has been diminished or changed in modern times.
Another theme could be the chaos that love can bring. 'Mad' often implies a lack of control, so the novel might show how love can disrupt lives, relationships, or a person's sense of self.

For instance, one character might give up a lucrative career opportunity in a far - off place to stay with the other. And also, loyalty could be a theme. The lovers remain loyal to each other through thick and thin, which is what makes their love eternal.
