I Unintentionally Cured The Grand Duke’s Insomnia


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

I possessed an extra young lady, Adelia Blaise, who did not appear in the original novel.

The male lead, who was called madman due to his severe insomnia, was destined to be saved by the female lead, the saint.

Since this had nothing to do with me, I was just planning to live by publishing a book.

But, the male lead suddenly appeared before me.

Of all things, holding the book that I had published with him as the subject.

Making all the excuses, I even read the book to prove my innocence.

“Don’t tell me you’re falling asleep… Huh?”

The male lead fell asleep.

“I’m not the one who saves you, Cain.”

“…That mouth.”

“You’ll meet a woman who’s much more benevolent and kinder than me, and she’ll save you…!”

“Shut up, Lia.”

The corners of his lips, which had been moving leisurely, twisted and rose.

“Okay, then let’s do this. The moment I leave this room, I’ll kill the woman you said is more benevolent and kinder than you.”

“…What, what did you say?”

“Bring as many people as you want.”


“Because there’s no one like you in this world.”

I was astonished to hear the male lead say that he would kill the heroine of the novel with his own mouth.

“You’ll be the one who will save me, Lia.”

…I think I twisted the original story.

I don't like how she's so convinced of their roles in the novel. Obviously, it's not set since she came in and took the place of a supposedly already dead and unnamed extra but insist on this thinking that it will go exactly as the novel. I think transmigrated girls who keep this kind of mind set is a bit annoying and s*upid.

Also, after waking up (history of 10 year illness), she's able for 3 months and the first thing she does is write a book about the duke which... more>> she published in 2 months? 😅 There are funny parts here and there. I like the ML so far. <<less

I always find characters who are completely convinced that the original story is some unavoidable fate to be incredibly annoying. Especially when they've already done things that don't match the OG story and are completely fine. It makes me think that they are incapable of critical thinking. The premise of the story, her publishing a book makes no sense at all. MC was someone who was bedridden for years and the first thing she does is publish a book? When she is the daughter of a wealthy count who adores... more>> her and does not have any real need to do so. She doesn't even seem to be particularly interested in writing so this just comes off as a very forced way to move the plot along. The MC's very blasé attitude towards using a real life person as a character in her book, even using their name, without their permission is very unlikeable. You would think that someone from the modern world would have more care towards another person's privacy. But no. She is completely okay with it, until she realises that it might have consequences for HER. What makes it worse is that she insists that she didn't want to get involved with the main characters. Overall I can't really recommend this story. <<less

I like the book so far, I think the FL is practical and compliant, if a bit of a pushover, which I think makes her compelling in a way where she feels grounded in reality. I like how the author so far has been showing us that the ML is getting more gentle with the FL as he's understanding her importance to him and enjoying her unique company and sense of humour. Rather than telling us, which again feels like more of a natural progression. We haven't seen the 'og'... more>> FL yet but I'm very curious to see the interaction there. <<less
