I just finished reading the novel and i can say that it is good, it's not your typical duke and count love story. I can also agree to some of the comments saying that in the manhwa she appears to be weak because she struggles so much in fighting the ML when he wakes up at night, in the novel it just states that they fought and the FL handle the ML flawlessly without any hardship as she always says that "he is much weaker at night" that's why i understand those who read the novel first. But over all it was a great novel to read, it pulls me out from my reading slump for weeks.
