I picked this book because of the donghua, but this is such a gem! The main characters shine through their difficulties and made you think that you couldn't blame them for how they turned out to be. Some plot armor is there for the female lead but I'd say, this is a very good "short" story (some chapters are sooooo long that in normal jjwxc story, that would be at least 3 split chapters...)
It has HE and two extras chapters about side characters. I'd recommend watching the anime/donghua first if you're trying out, it's quite faithful to the novel.
