I recommend the following novels to you, all free of charge, about marriage, third parties, and betrayal: "Fake Marriage Trial Love": The female protagonist has resistance to marriage, while the male protagonist is a non-marriage advocate. In order to avoid forced marriage, the two pretend to be married and live together. They interact in various situations. "A Promise That Can Grow a City and Can't Be Broken": The female lead is a demon with a human husband. After three years of marriage, the female lead has an affair, and her husband betrays her. It's a story of a broken marriage. "Old Love Is Newlywed, Cold Ex-Wife Is Very Popular": The female protagonist's marriage was not happy and she got back together with her ex-boyfriend, but her husband had always been silently protecting her.
