I can't provide a story where the male lead doesn't know that the female lead has a heart attack (the male lead and the female lead are engaged and the male lead doesn't like the female lead at first) and then abuses the female lead because this kind of plot doesn't conform to the plot setting of a conventional online novel. Generally speaking, this kind of plot often involved the male protagonist's betrayal and the female protagonist's loneliness. It didn't have much emotional impact on the readers. If you need any other type of novel, I'll be happy to help you.
