If you want to understand the ending of the novel's cheating theme in the context of a marriage war, then I recommend you to read " At the Finale, the Villain Female Lead Wants to Kill Me!" This was an Oriental fantasy novel. The male protagonist in the novel was a failed author. Towards the end of his novel, a woman in an ancient robe appeared out of thin air in front of him and threatened him not to let the Demon Sect she belonged to fail, or she would take his life. The male protagonist saw that the novel had been rewritten and the plot had completely collapsed, but the female protagonist still wanted to kill him. At the end of the novel, the male protagonist chose a different ending under the influence of the female protagonist. The female protagonist also gave up the idea of killing him. I hope my recommendation can meet your needs.
