A Faint Dream, Elusive Memories of the Past

The heroine and the hero are probably not against the rules of heaven when they are together. The heroine's parents are directly the sworn enemies of the heroine. In the past, the female protagonist faced all kinds of humiliation from the male protagonist, refused to save her, and even protected the mistress. Later, the male protagonist gave up on the female protagonist and completely ignored the male protagonist's objections and forced her to stay by her side. The male protagonist keeps saying that he doesn't want to hurt other people, but that doesn't mean the female protagonist is merciful and everyone around him is dead. The supporting character obviously has a normal relationship with the male protagonist but can risk his life to help the male protagonist deal with the female protagonist. They are all fake people.
