I Love Eating Salty Dried Chinese Plums
I'm a bit confused or perhaps I wasn't reading properly, so it's the protagonist of the story who was the villain in the novel a good person or bad?
The MC was been in this world for around ten years, so while he pretends to be like his villain novel counterpart would it's inevitable that his true self would slip through sometimes. This pill incident probably never happened originaly, but the MC being a good guy "went out of character" and helped them out with the pills. There's probably more moments like this.
