It’s kinda hard to say because the novel and the manhwa go in pretty different directions. It’s probably around chapter 30 or so ( take this with a grain of salt I don’t fully remember), but I’d honestly recommend starting from the beginning. They changed a lot of the story in the manhwa, so it’s hard to say exactly where you should pick up the novel.

Hello to my lovelies. This manhwa has been discontinued but it does have a novel that is completed hehe
